@Cartoonyworld109 This is correct. With small telescopes, under 1500mm of focal length, the planets seems to be very small. The cartoon effect may be due to low contrast images. Newtonian reflector telescopes use to deliver low contrast images due to their central obstruction by secondary mirror.
@Charrister i'm not sure the proper names of these filters, but they're pretty much just coloured lenses you screw into your eyepiece. i bought a set with 10 or 12 different colours, and the blue definitely works best for Jupiter. it really brings out the cloud bands.
plus it's fun trying different filters on various objects. i tried the red one on the Moon and it looked like candy haha.
One poster mentioned the best temp for telescopic observation 70f. Profoundly wrong. Excellent seeing can be had at zero degrees. The jetstream overhead and thermal equilibrium of optics are what matters. Local seeing thats controllable is paramount too. There is no best temp.
Cold nights aren't good for viewing the planets as a disk. The air causes a lot of turbulence and distortion that comes in on larger telescopes. The best temperature for viewing planets is about 70° F. (21° C)
hey im considering getting an 8 inch Dobsonian reflector and im just wondering what the lens size (6mm, 8mm, 10mm, 17mm and so on...) effects the image. like, what size lens is best for viewing planets, stars and so on.
WoW!! thats thru a 6inch or was that zoomed in? If it wasnt zoomed in i wonder what it will look like in my 12 Dob when i get it in Sept. Thats Awesome!!
@CumputerPhysiscsLab On a better night. On the same night, the 6 might be better. Larger aperture is more sensitive to turbulence. I mask our 16 to 6" when turbulent. You could make a 4"or 5" off-axis mask and realy get some nice views when the seeing is not best. A 5" off-axis unobstructed reflector is a fine thing. A 12 is a nice scope...
@appleipodtouch2g The image through an 8 inch telescope should be a bit better than this one made through a 6 inch. A bit more detail should be visible.
@fjbutch - You should be able to see Jupiter in the mornings right now, but you have a pretty strong jet stream going on so it probably won't look good.
@CmdrGendoIkari Much appreciated !!...My young son and I went out this morning and saw Jupiter plus her 3 moons. We have beautiful clear skies here in NZ, and even saw Jupiter's stripes and the great red spot momentarily... Thanks again... cheers :)
@Melimo The picture shows the clouds in Jupiter. You see them moving due to planet's rotation, very fast. From Jupiter we can only see the visible light that reflects from the Sun, no radiation of any other kind.
@Melimo I say no. Although Jupiter's clouds do move very fast, they're still too slow to be seen like this in real time. The motion in this video is caused by the shimmer of Earth's atmosphere.
@Melimo I understand you're wondering about the blurriness ("boiling" effect) of the image. This is not because of Jupiter, but cause of Earth's heated atmosphere. That's why winters are always better for skyviewing. Another tip is to track objects that are high on the sky, and not close to the horizon, because in the horizon you're targeting in more thick layers of atmosphere, and the "boiling" image phenomenon becomes more intense.
@CumputerPhysiscsLab i just brought a 10" saxon dobsonian. What eyepieces or filters do i need to get to view saturn like this? i have a 25mm plossil,10mm plossil, and a 6.5 wide view plossil. I can see the rings and all, but not like that. it shows up as a little white ball with rings around it. :) was just wondering how do i get to see it closer up and with more detail.
@MrSquareyez Probably your telescope is 1500mm focal length, so a 6.5 mm eyepiece would yield 230x. The details that shows this video can be spotted at 230x magnification, but you will see the disc of Jupiter apparently smaller than here. To see a big disc of Jupiter you need at least 500x. You may use a barlow with the 6.5 mm eyepiece to reach 500x. Nevertheless to spot details on the planet depends on atmospheric turbulence, much more than on magnification. Wait for a good night...
@CumputerPhysiscsLab its 1200mm focal length. i actually put this in the wrong video lol. was suppose to put this in your saturn video. But still the same prinicple. I did try what you said tho, 3x barlow lense with my 6.5 wideview eyepiece. still only showed up as a smaller version of our moon, but with rings. It'd be nice to see the colours in it instead of like a white glow, star like image. If you know what i mean :)
@MrSquareyez Yes, you will never see through a telescope a planet as big as the Moon. They are really far and to the naked eye they are just a pinpoint bright star. The only option to see a planet really big through a telescope is using very very large telescopes, at least 40 inches of aperture or more, but that is out of scope for amateur astronomy.
With regards to viewing galaxies and fainter nebulae, is this possible using a six inch scope under darker skies? Or is it simply a case of needing greater aperture?
@britishbulldog5505 It is possible indeed seeing galaxies with a 6 inch telescope. Last week I saw M51, the Whirlpool galaxy under dark skies using a 6 inches refractor telescope. Big and bright galaxies (most of messier catalog) are visible with telescopes from 4 to 6 inches of aperture. Important thing is to avoid light pollution.
All Telescopes that are Manufactured as Manual "Diffraction Limited" means your Telescopes are design 100% Text-Book Perfection Dawes Resolution for their Apertures,i.e. 0.57 ArcSeconds 8" or 0.8 ArcSeconds 6".What MOST Amateur Astronomers FORGET is the BASIC LAW that you MUST give a"Cool Down Period" of 20 minutes or better,to REMOVE ALL AIR Temperature TURBULENCE Currents in your Scopes to Achieve Dawe's Diffraction Limited Resolutions! Then you will see,Backyard Views just like Jupiter Video!
Wow, nice! I'm a little new to the hobby, and have never had a view like this, even in my 8" Dob. How can I get my view like this? Even with my 9mm, it doesn't even compare to this! I'd love some tips, thanks!
@dudewithtelescope With an 8 inch dobson you should get even more details and resolution than with my 6 inch. First tip is observing Jupiter at opposition, in order to catch the planets when its apparent size is largest. Second tip is to have the telescope very well collimated. This is important to get sharp focus. Third tip is to spend time observing only on low turbulence nights. Fourth tip is not to observe above hot roofs in the city, because that spoils completely the image. Hope it helps!
@CumputerPhysiscsLab hi i live in a city and looking to get into this sorta thing. wanting to get this sort of view / maybe clearer? - but what sort of telescope can i get - lots of the names etc mean jibberish to me at moment cause i have no clue :)
@shinraninja Probably best choice is a small refractor around 100mm (4 inches) of aperture, or a small reflector around 6 inches (150mm) of aperture. Bigger telescopes are difficult to use in a city unless you have a big place to use them.
@CumputerPhysiscsLab I have a question, i have bought 2 days ago a 5.1 inch telescope ,i live in a city and ive been searching for 2 days now, i was able to track Jupiter with a 10mm eye piece and also Saturn, but i never got even close in seeing anything close to a nebula or a galaxy, is it because of my telescope, because of the fact that i live in a city, or because i havent been searching for long?
@Napoleontas It is very difficult to see nebulae or galaxies from a city with a telescope. Some people is using special filters to see them from light-polluted skies, but nevertheless the best way to see them is observing from a dark place out of the cities.
You think so heh? I will try it in my village, do you think that buying a 10 inch telescope will give me a great difference from the one i already have?
Also what do you think about colored filters, nebula filters and sun filters, do they worth their money? I want to buy a Barlow lens now because iam not satisfied with the 112 times magnification that i can achieve with my 6mm eye piece, my telescope is f=650
@Napoleontas You will see a lot more in your village. Dark skies make a great difference. Under dark skies there is also a big difference between watching deep sky objects through a 6 inch than through a 10 inch. A 10 inch gathers 3 times more light than a 6 inch telescope. Nevertheless if you could go to a star party, you will test by yourself the difference when watching through bigger apertures at no cost. This is advisable before shopping new telescopes.
@CumputerPhysiscsLab In what magnification do you suggest that the planets should be viewed?
For eg i have 112 times magnification as i have told you but saturn looks really small, disappointingly small in fact. I will buy a Barlow lens to double that but do you think that i should buy some kind of filter?
@Napoleontas At least 250x. On nights with low turbulence, you may achieve up to 500x comfortably. When using 250x or more you may see many interesting features in planets: Cassini division and storms in Saturn, red spot and bands in Jupiter, and so on.
@CumputerPhysiscsLab i Have just bought a Barlow lens i have a 216 times magnification, but it is a bit blurry even at this magnification(wondering what will happen with even higher mangification) and iam still not sutisfied by what i see, for eg if saturn appeared that the size of your videos jupiter i would be perfectly happy, but i dont know, i calculate that in order to see something like that you will have to have a big telescope bigger than my own 130mm and 500+ magnification.
@Napoleontas It is not easy to get sharp images under big magnification. First cause is atmospheric turbulence. If you see planets over the roofs of your neighbors you will always see blurry images. The best place to see planets is over a lawn and a clear horizon. Lawn does not radiate heat at night, so you will enjoy a less turbulence atmosphere. Under good seeing conditions, a 130mm telescope could reach 500x magnification and (not razor but) sharp images. Try going out of the city...
@CumputerPhysiscsLab I will definitely try it in my village after what you have told me and i thank you very much for your suggestions, i am new to this "hobby" and iam just learning, your help is really useful.I already have a 2x Barlow lens and 3 eye pieces one 10mm , one 6mm and one 25mm, my telescope is f=650 and as i have told you 130mm, the maximum that i can get in magnification is from the combination of barlow and the 6mm ,216, what do you suggest that i should buy to improve my system?
@Napoleontas A fast and cheap solution would be stacking 2 barlow lenses. That would yield a magnification of 450x. It is not advisable to increase more the magnification because even under perfect skies, you would get blurry images, due to the diffraction effect on the limited aperture of 130mm of your telescope.
@Napoleontas Yes, Dobsonians are a very good option. They are cheap and more ready to use. Very good for visual deep sky and just good for visual planetary, due to their short focal lengths. I have a 16 inch Dobson that has a very good optics quality, a Meade Lightbridge. Astrophotography is a nightmare, because Dobson telescopes are designed to be used visually. Nevertheless, on visual a Dobson telescope can give you very good results. Fast, easy, cheap and powerful.
@CumputerPhysiscsLab Yes indeed thats what caught my attention the cheapness of the Dobsonians, and their size in inches , for eg as you would know , a 12 inch dobsonian is far cheaper than a celestron cassegrain for eg. My personal interest are firstly the planets secondly the deep sky objects, but i want a clear image of planets and a big one so that i could see the atmospheric features of jupiter for eg. My next move will be the 10 inch dobsonian
@Napoleontas A Celestron cassegrain it's a bit better for planets than a Dobson for 2 reasons: large focal length that makes easier to reach high magnifications and motorized mount that avoids the planet getting out of the field of view while observing. Tracking a planet through high magnification (200x or more) may be difficult at first using a Dobson telescope. In regards to optics and image quality, results may be quite similar in both kind of telescopes. Prices are very different.
@CumputerPhysiscsLab I ask you because iam starting to get a bit frustrated(i dont have a constant income so i want to buy things that will worth my mone), i have already spend 290 euros for the telescope and 88 euros for the 6mm lens and the 2x Barlow, and i dont have what i want yet. Should my next move be a smaler mm eye piece such as 3mm or something, or a bigger Barlow?
@Napoleontas Usually very short focal length eyepieces are very uncomfortable to observe with, due to their also short eye relief. So the better way to get higher magnification would be to stack another barlow lens.
@CumputerPhysiscsLab Quote "Fourth tip is not to observe above hot roofs in the city, because that spoils completely the image" I did never realize. Thanks for the hint.
@dudewithtelescope Hi. I also have a 8" Dob. The only problem with it is that it doesn't track the stars so the more the magnification, the more it'll fly across the field of view. But it's not all bad news because the more the magnification, the dimmer the image in ANY telescope.
I tend to use 12-25mm. The 9mm eyepiece supplied with the telescope isn't probably the best. The 10mm I have is rubbish. :)
I've bought a webcam so will be modifying it soon for astrophotography.
@dudewithtelescope This is Lunar Astro-Photographer of ASTRONOMY Magazine December 1982 BackIssues, section "A Years Harvest of Pictures". I am Astro-Photographer, C'est Le Jules VERNE,C'est Le Jules VIEIRA from Europe Charles MESSIER to CANADA. In Primary, You should have seen images like this of Jupiter through your Newtonian Parabolic 8" Dobsonian. The reason you did NOT,was because You did NOT give 20 Full minutes for your Newtonian to culimate or "Cool Down to you Ambient Air Temperature."
@dudewithtelescope Continued, Amateur Astronomer Mr. dudewithtelescope. All Newtonian Parabolic Newtonians are "Diffraction Limited" or shoulb BE Computerized 1/8 Wave Accuracy Minimum to achieve :"Diffraction Limited Optics". Assuming your Dob 8" Parabolic Newtonian is Diffaction Limited , you will "Visually" reach 0.57 Arcsecond Dawes Resolution 8" as opposed to 0.8 ArcSecond Resolution on a 6" Scope. If you did NOT see Jupiter as in the Video,"Visually". It is because, NO "Cool Down" Time
@CumputerPhysiscsLab Ιt' s a 6'' refractor or 6" Newtonian reflector??? I don' t thing that someone can catch so sharp images with a common reflector.... Anyway, Congratulations!!!!
@PARLAPIPA123 Wow! Excellent job! With a 8'' inch Newtonian, F6 (focal length) a good mount, a famous eyepiece at 8mm, But, I can' t have your results... Also, I am at a good altitude (about 40 degrees from equator and 700m up to sea), in a dark area with good seeing and even at the latest opposition the Jupiter was blurred... What kind of camera did you use??
@PARLAPIPA123 sorry I haven' t seen the comments about the camera.... I want to believe that my camera is the problem... ok, I am waiting to read your article in the next Sky & Telescope issue....
@CumputerPhysiscsLab Sorry im new to this, i have a canon 7d and i wish to film though a telescope, how do you do it. do i need some kind of adapter in the eye piece or something.??
how much magnification was that on this video because i got a 6 inch telescope for a 1-2 weeks ago the focal lenght of it is 1400 (f9.3) and the diameter of it is 150mm scope
@jack342able This is a 6 inches telescope working probably around 3000 mm focal length. So, it is equivalent to your telescope using a 2x barlow lens.
hey man, could you reply to this message and just say hi or something- i wana ask you a few questions about telescopes so i just wna know if you do reply. thanks
@Ozzrya91 It depends on the conditions. For bad seeing areas, smaller telescopes with better optics are preferred. This is why I ordered a 6" Mak for planetary photography. More aperture gathers more atmospheric movements. Anyway, I hope you enjoy your dobsonian, I guess it gives great views :)
can you see jupiter's red spot with a 4.5 inch, I have never seen it before, I have two tube telescopes, one is 2.5 inches the other is 2.7 inches, they show jupiter two small to see the spot, so I wonder what it looks like in a 4.5 inch, whic is the only type I can afford, most 6 inch and higher are too expensive for me to afford.
@Akirameerkat I can see the Great Red Spot sith a 6-inch telescope, visually and photographically. Nevertheless, maybe it is possible to observe it with a 4 inch telescope under very good seing atmosphere.
@Akirameerkat I have seen the Great Red Spot in a 2.5" refractor. OK, so it was a Zeiss, and the seeing needs to be very good, but it can be done. Magnification was 140x or so. You need to have some experience as an observer to spot the GRS in such a small telescope. It is easier in a larger one, of course.
@MrAstrojensen I can't magnify rhat much, I have a 4mm is the greatest magnification I have, thats 125x, but it can't focus, I went to my collage to see the spot, but in there 8 inch celestron, it looks like a tiny grey smuge and was very hard to see.
@Akirameerkat Yes you can see the Red Spot with a 4.5" in good skies and the higher the planet the better seeing will be. It also helps to have young eyes... I have still my 40 year old 4.5 inch Tasco reflector. When I was young I could see the Giant Red Spot and shadow of a moon on Jupiter on a cold night. Good skies is an essential condition because even larger scopes will have trouble in poor skies. The planet should be high in the sky in calm weather, not too hot, for good seeing.
@jdastro I am 21, I still don't have a 4 inch telescope yet, as there isn't a place anywhere in my county that has telescopes for sale of that size, I will have my 2 inch ones, when ever I look at jupiter, I just see a while ball, with one line on the top, and the moons around it, if one is in font, I can't see it, in the collage they have better 6 inch telescopes, but it was very hard to see the spot, I think it looked like a grey smudge, very difficult to see.
What DSLR are you running? How are you attaching it to the scope? Prime focus or through the EP? I am curious because I have a decent DSLR and would like to get some nice images, being that my scope is only a 125 I dont know what kind of results to expect. I wish I still had my Hardin Dob, damn hurricane Katrina took her from me.
People need to learn the basics of telescopes before spouting off ignorant statements. Just because the Tasco telescope you got for Christmas was a POS doesnt mean that a decent telescope of any size in the right hands with the right conditions cant produce a GREAT image. If you dont have anything intelligent to say I suggest you STFU and learn. That being said, NICE VIDEO!
Depending on the optical quality and seeing, I think you will be impressed! I had a 8" dob at one time and the views were excellent, I now have a 1000 ETX 125 and it doesnt compare to the old dob. I am going to get another ASAP and put the ETX in the closet, Lol!
I observed Jupiter through a cheap relecting telescope and was able to see the bands quite clearly. What was also amazing were the moons orbiting the planet, which appeared as tiny bright white stars. It was awesome. I manged to see this for about 30 seconds then the clouds came and that was it.
@clayxtr The telescope does not determine the magnification, it only allows to have more MAXIMUM magnification. The lens is what magnifies, and you can use many different lenses to achieve different magnifications.
This video is not fake, I can see the same image with a 5mm lens on a 5" reflector.
I beg to differ, the eye piece is only part of the equation, the telescope's focal length is a MAJOR part of the magnification, to get the magnification take the focal length of the telescope and divide it by the power of the eye piece. For instance if your telescopes focal length is 1000 and your ep is 10mm then your magnification is 100x. The more you magnify the less light is going to reach your eye, throw a barlow in the mix and the light is GREATLY diminished.
@bayouastro Every thing you said in your comment is basic knowledge.. Yes, I know my comment was a bit wrong, but I am not the greatest at putting what is in my head into words.
@Galacticmaster The best 4-5 inches telescopes for planets are refractors and maksutovs. You have good quality refractors and good prices at Celestron. At Orion you will find at good price Maksutovs.
@clayxtr the aperture sizes you are talking about does not contribute to the size of the image, the reason that this image is larger is because of the lens this person was using, not because of the size of their telescope
I used a 14mm eyepiece for proyection to the camera, no barlow. The focal length of the telescope is 750mm, and the eyepiece has an equivalent effect to a barlow 2x, more or less.
@CumputerPhysiscsLab I am plannin to buy my first telescope, have just started the hobby of stargazin, i would like to know all of the technical specifications of the telescope you used, wanna know as much as possible before i take a plunge.. please help
@hummerume For a first time scope, the best option is a small refractor. They are not expensive. You have for example a Skywatcher SW 80AR-AZ4 for 179 US$ at Amazon. Nevertheless I tell you the specs of my scope: It is a Newton reflector 6 inches diameter and 750mm focal length. I have no equatorial mount for this scope so I hold it over a photographic tripod.
@CumputerPhysiscsLab Hey thanks for the quick response, and for the suggestion as well. i will do some homework on your suggestion.... thanks again buddy..
@CumputerPhysiscsLab Are you sure? I think your first scope depends on a couple aspects. 1. Are you using this scope for planetary and lunar use, or deep space objects? 2. Portability. Are youy planning on transporting your scope. 3. Ambition. If you plan to get into this subject i would consider getting a better quality scope. If you just want a small scope for when friends and family come over and want to see the planets you dont need a large scope. 4. Goto or manual.
@CumputerPhysiscsLab If you want to see deep space objects like the messier list it is goot to have a newtonian with atleast 6 inches of aperature. If you want to view the planets and the moon i suggest either a 4.5 inch reflector or an 80mm refractor. If you are only going to use the scope on occasion it is a waste of money to spend 500 dollars on a large scope. Also keep in mind tripods. Alt az are easy to use compared to more complicate equatorials but eq mounts can be used to track objects.
@CumputerPhysiscsLab how do you manage to track Jupiter if you use it over a simple tripod? i know you have told it is without tracking. but Jupiter will vanish out of the FOV in this magnification in just seconds, if not tracked.
he has zoomed in on jupiter with his camera. and this might even be a Schmidt Cassagrain Telescope. Not a dobsonian. Dobsonians are not meant for high magnification. they can be but they are mostly for nebulae galaxy and star clusters.
Thanks for the info! I never knew that! I learn something new everyday! I have always wondered why my 8' inch schmidt cassegrain has more focal length than regular 8' newtonian reflectors and dobsonians. Now i know! Also schmidt cassegrains have longer focal ratios! That means less brighter! So dobsonians are more Convenient for Deep sky observing and schmidt are for both deep sky observing and high mag! Planets and moon! But both fair equally. But schmidt cassegrains can get higher mag easily!
Brightness depends only on aperture. A 10" SCT should have the same light gathering power as a 10" reflector. However a 10" SCT although a shorter tube probably weighs as much if not more than a 10" reflector tube. The longer FL means a more narrow FOV. A dobsonian with a f/5 will have a much bigger FOV than an f /10 SCT.
Still stunning though dont you agree?

CumputerPhysiscsLab 6 months ago 3
@CumputerPhysiscsLab On a better night. On the same night, the 6 might be better. Larger aperture is more sensitive to turbulence. I mask our 16 to 6" when turbulent. You could make a 4"or 5" off-axis mask and realy get some nice views when the seeing is not best. A 5" off-axis unobstructed reflector is a fine thing. A 12 is a nice scope...

Are we seeing the cloud movement on Jupiter, or is that more the radiation activity coming from the planet?
Melimo 7 months ago 2
@Melimo The picture shows the clouds in Jupiter. You see them moving due to planet's rotation, very fast. From Jupiter we can only see the visible light that reflects from the Sun, no radiation of any other kind.

@CumputerPhysiscsLab Thanks! Obviously I'm no astronomer, or physics genius, haha!
MelonJMusic 7 months ago
@Melimo I say no. Although Jupiter's clouds do move very fast, they're still too slow to be seen like this in real time. The motion in this video is caused by the shimmer of Earth's atmosphere.
Axgoodofdunemaul 6 months ago
@Melimo I understand you're wondering about the blurriness ("boiling" effect) of the image. This is not because of Jupiter, but cause of Earth's heated atmosphere. That's why winters are always better for skyviewing. Another tip is to track objects that are high on the sky, and not close to the horizon, because in the horizon you're targeting in more thick layers of atmosphere, and the "boiling" image phenomenon becomes more intense.

@CumputerPhysiscsLab i just brought a 10" saxon dobsonian. What eyepieces or filters do i need to get to view saturn like this? i have a 25mm plossil,10mm plossil, and a 6.5 wide view plossil. I can see the rings and all, but not like that. it shows up as a little white ball with rings around it. :) was just wondering how do i get to see it closer up and with more detail.
MrSquareyez 7 months ago
@MrSquareyez Probably your telescope is 1500mm focal length, so a 6.5 mm eyepiece would yield 230x. The details that shows this video can be spotted at 230x magnification, but you will see the disc of Jupiter apparently smaller than here. To see a big disc of Jupiter you need at least 500x. You may use a barlow with the 6.5 mm eyepiece to reach 500x. Nevertheless to spot details on the planet depends on atmospheric turbulence, much more than on magnification. Wait for a good night...
CumputerPhysiscsLab 7 months ago
@CumputerPhysiscsLab its 1200mm focal length. i actually put this in the wrong video lol. was suppose to put this in your saturn video. But still the same prinicple. I did try what you said tho, 3x barlow lense with my 6.5 wideview eyepiece. still only showed up as a smaller version of our moon, but with rings. It'd be nice to see the colours in it instead of like a white glow, star like image. If you know what i mean :)

@MrSquareyez Yes, you will never see through a telescope a planet as big as the Moon. They are really far and to the naked eye they are just a pinpoint bright star. The only option to see a planet really big through a telescope is using very very large telescopes, at least 40 inches of aperture or more, but that is out of scope for amateur astronomy.

With regards to viewing galaxies and fainter nebulae, is this possible using a six inch scope under darker skies? Or is it simply a case of needing greater aperture?
britishbulldog5505 7 months ago
@britishbulldog5505 It is possible indeed seeing galaxies with a 6 inch telescope. Last week I saw M51, the Whirlpool galaxy under dark skies using a 6 inches refractor telescope. Big and bright galaxies (most of messier catalog) are visible with telescopes from 4 to 6 inches of aperture. Important thing is to avoid light pollution.

All Telescopes that are Manufactured as Manual "Diffraction Limited" means your Telescopes are design 100% Text-Book Perfection Dawes Resolution for their Apertures,i.e. 0.57 ArcSeconds 8" or 0.8 ArcSeconds 6".What MOST Amateur Astronomers FORGET is the BASIC LAW that you MUST give a"Cool Down Period" of 20 minutes or better,to REMOVE ALL AIR Temperature TURBULENCE Currents in your Scopes to Achieve Dawe's Diffraction Limited Resolutions! Then you will see,Backyard Views just like Jupiter Video!

Wow, nice! I'm a little new to the hobby, and have never had a view like this, even in my 8" Dob. How can I get my view like this? Even with my 9mm, it doesn't even compare to this! I'd love some tips, thanks!
dudewithtelescope 10 months ago 2
@dudewithtelescope With an 8 inch dobson you should get even more details and resolution than with my 6 inch. First tip is observing Jupiter at opposition, in order to catch the planets when its apparent size is largest. Second tip is to have the telescope very well collimated. This is important to get sharp focus. Third tip is to spend time observing only on low turbulence nights. Fourth tip is not to observe above hot roofs in the city, because that spoils completely the image. Hope it helps!

@CumputerPhysiscsLab hi i live in a city and looking to get into this sorta thing. wanting to get this sort of view / maybe clearer? - but what sort of telescope can i get - lots of the names etc mean jibberish to me at moment cause i have no clue :)
shinraninja 8 months ago
@shinraninja Probably best choice is a small refractor around 100mm (4 inches) of aperture, or a small reflector around 6 inches (150mm) of aperture. Bigger telescopes are difficult to use in a city unless you have a big place to use them.
CumputerPhysiscsLab 8 months ago
@CumputerPhysiscsLab I have a question, i have bought 2 days ago a 5.1 inch telescope ,i live in a city and ive been searching for 2 days now, i was able to track Jupiter with a 10mm eye piece and also Saturn, but i never got even close in seeing anything close to a nebula or a galaxy, is it because of my telescope, because of the fact that i live in a city, or because i havent been searching for long?
Thank you
Napoleontas 8 months ago
@Napoleontas It is very difficult to see nebulae or galaxies from a city with a telescope. Some people is using special filters to see them from light-polluted skies, but nevertheless the best way to see them is observing from a dark place out of the cities.
CumputerPhysiscsLab 7 months ago
@CumputerPhysiscsLab Thank you very much for your answer.
You think so heh? I will try it in my village, do you think that buying a 10 inch telescope will give me a great difference from the one i already have?
Also what do you think about colored filters, nebula filters and sun filters, do they worth their money? I want to buy a Barlow lens now because iam not satisfied with the 112 times magnification that i can achieve with my 6mm eye piece, my telescope is f=650
Napoleontas 7 months ago
@Napoleontas You will see a lot more in your village. Dark skies make a great difference. Under dark skies there is also a big difference between watching deep sky objects through a 6 inch than through a 10 inch. A 10 inch gathers 3 times more light than a 6 inch telescope. Nevertheless if you could go to a star party, you will test by yourself the difference when watching through bigger apertures at no cost. This is advisable before shopping new telescopes.
CumputerPhysiscsLab 7 months ago
@CumputerPhysiscsLab In what magnification do you suggest that the planets should be viewed?
For eg i have 112 times magnification as i have told you but saturn looks really small, disappointingly small in fact. I will buy a Barlow lens to double that but do you think that i should buy some kind of filter?
Napoleontas 7 months ago
@Napoleontas At least 250x. On nights with low turbulence, you may achieve up to 500x comfortably. When using 250x or more you may see many interesting features in planets: Cassini division and storms in Saturn, red spot and bands in Jupiter, and so on.
CumputerPhysiscsLab 7 months ago
@CumputerPhysiscsLab i Have just bought a Barlow lens i have a 216 times magnification, but it is a bit blurry even at this magnification(wondering what will happen with even higher mangification) and iam still not sutisfied by what i see, for eg if saturn appeared that the size of your videos jupiter i would be perfectly happy, but i dont know, i calculate that in order to see something like that you will have to have a big telescope bigger than my own 130mm and 500+ magnification.
Napoleontas 7 months ago
@Napoleontas It is not easy to get sharp images under big magnification. First cause is atmospheric turbulence. If you see planets over the roofs of your neighbors you will always see blurry images. The best place to see planets is over a lawn and a clear horizon. Lawn does not radiate heat at night, so you will enjoy a less turbulence atmosphere. Under good seeing conditions, a 130mm telescope could reach 500x magnification and (not razor but) sharp images. Try going out of the city...
CumputerPhysiscsLab 7 months ago
@CumputerPhysiscsLab I will definitely try it in my village after what you have told me and i thank you very much for your suggestions, i am new to this "hobby" and iam just learning, your help is really useful.I already have a 2x Barlow lens and 3 eye pieces one 10mm , one 6mm and one 25mm, my telescope is f=650 and as i have told you 130mm, the maximum that i can get in magnification is from the combination of barlow and the 6mm ,216, what do you suggest that i should buy to improve my system?
Napoleontas 7 months ago
@Napoleontas A fast and cheap solution would be stacking 2 barlow lenses. That would yield a magnification of 450x. It is not advisable to increase more the magnification because even under perfect skies, you would get blurry images, due to the diffraction effect on the limited aperture of 130mm of your telescope.
CumputerPhysiscsLab 7 months ago
@CumputerPhysiscsLab I have spotted a good dobsonian 10inch which is cheap enough.
Whats your opinion about Dobsonians, do they worth their money?
Thank you.
Napoleontas 7 months ago
@Napoleontas Yes, Dobsonians are a very good option. They are cheap and more ready to use. Very good for visual deep sky and just good for visual planetary, due to their short focal lengths. I have a 16 inch Dobson that has a very good optics quality, a Meade Lightbridge. Astrophotography is a nightmare, because Dobson telescopes are designed to be used visually. Nevertheless, on visual a Dobson telescope can give you very good results. Fast, easy, cheap and powerful.
CumputerPhysiscsLab 7 months ago
@CumputerPhysiscsLab Yes indeed thats what caught my attention the cheapness of the Dobsonians, and their size in inches , for eg as you would know , a 12 inch dobsonian is far cheaper than a celestron cassegrain for eg. My personal interest are firstly the planets secondly the deep sky objects, but i want a clear image of planets and a big one so that i could see the atmospheric features of jupiter for eg. My next move will be the 10 inch dobsonian
Napoleontas 7 months ago
@Napoleontas A Celestron cassegrain it's a bit better for planets than a Dobson for 2 reasons: large focal length that makes easier to reach high magnifications and motorized mount that avoids the planet getting out of the field of view while observing. Tracking a planet through high magnification (200x or more) may be difficult at first using a Dobson telescope. In regards to optics and image quality, results may be quite similar in both kind of telescopes. Prices are very different.
CumputerPhysiscsLab 7 months ago
@CumputerPhysiscsLab i will buy a second barlow and i will see what kind of results i will get
Napoleontas 7 months ago
@CumputerPhysiscsLab I ask you because iam starting to get a bit frustrated(i dont have a constant income so i want to buy things that will worth my mone), i have already spend 290 euros for the telescope and 88 euros for the 6mm lens and the 2x Barlow, and i dont have what i want yet. Should my next move be a smaler mm eye piece such as 3mm or something, or a bigger Barlow?
Napoleontas 7 months ago
@Napoleontas Usually very short focal length eyepieces are very uncomfortable to observe with, due to their also short eye relief. So the better way to get higher magnification would be to stack another barlow lens.
CumputerPhysiscsLab 7 months ago
@CumputerPhysiscsLab Thats indeed true i have realized that .
But the stupid thing that i have done is to buy a 2x barlow when what i really needed was at least a 3x...
I couldnt calculate the difference of 2x giving my lack of experience and i thought 2x was suffice enough.

AndyFlash0f 10 months ago
@dudewithtelescope Hi. I also have a 8" Dob. The only problem with it is that it doesn't track the stars so the more the magnification, the more it'll fly across the field of view. But it's not all bad news because the more the magnification, the dimmer the image in ANY telescope.
I tend to use 12-25mm. The 9mm eyepiece supplied with the telescope isn't probably the best. The 10mm I have is rubbish. :)
I've bought a webcam so will be modifying it soon for astrophotography.

@Akirameerkat I have seen the Great Red Spot in a 2.5" refractor. OK, so it was a Zeiss, and the seeing needs to be very good, but it can be done. Magnification was 140x or so. You need to have some experience as an observer to spot the GRS in such a small telescope. It is easier in a larger one, of course.

@MrAstrojensen I can't magnify rhat much, I have a 4mm is the greatest magnification I have, thats 125x, but it can't focus, I went to my collage to see the spot, but in there 8 inch celestron, it looks like a tiny grey smuge and was very hard to see.
Akirameerkat 1 year ago
@Akirameerkat Yes you can see the Red Spot with a 4.5" in good skies and the higher the planet the better seeing will be. It also helps to have young eyes... I have still my 40 year old 4.5 inch Tasco reflector. When I was young I could see the Giant Red Spot and shadow of a moon on Jupiter on a cold night. Good skies is an essential condition because even larger scopes will have trouble in poor skies. The planet should be high in the sky in calm weather, not too hot, for good seeing.

@clayxtr The telescope does not determine the magnification, it only allows to have more MAXIMUM magnification. The lens is what magnifies, and you can use many different lenses to achieve different magnifications.
This video is not fake, I can see the same image with a 5mm lens on a 5" reflector.
Goalatio 1 year ago
@Goalatio
I beg to differ, the eye piece is only part of the equation, the telescope's focal length is a MAJOR part of the magnification, to get the magnification take the focal length of the telescope and divide it by the power of the eye piece. For instance if your telescopes focal length is 1000 and your ep is 10mm then your magnification is 100x. The more you magnify the less light is going to reach your eye, throw a barlow in the mix and the light is GREATLY diminished.

@CumputerPhysiscsLab Are you sure? I think your first scope depends on a couple aspects. 1. Are you using this scope for planetary and lunar use, or deep space objects? 2. Portability. Are youy planning on transporting your scope. 3. Ambition. If you plan to get into this subject i would consider getting a better quality scope. If you just want a small scope for when friends and family come over and want to see the planets you dont need a large scope. 4. Goto or manual.
hiian123 1 year ago
@CumputerPhysiscsLab If you want to see deep space objects like the messier list it is goot to have a newtonian with atleast 6 inches of aperature. If you want to view the planets and the moon i suggest either a 4.5 inch reflector or an 80mm refractor. If you are only going to use the scope on occasion it is a waste of money to spend 500 dollars on a large scope. Also keep in mind tripods. Alt az are easy to use compared to more complicate equatorials but eq mounts can be used to track objects.
hiian123 1 year ago
@CumputerPhysiscsLab how do you manage to track Jupiter if you use it over a simple tripod? i know you have told it is without tracking. but Jupiter will vanish out of the FOV in this magnification in just seconds, if not tracked.

Thanks for the info! I never knew that! I learn something new everyday! I have always wondered why my 8' inch schmidt cassegrain has more focal length than regular 8' newtonian reflectors and dobsonians. Now i know! Also schmidt cassegrains have longer focal ratios! That means less brighter! So dobsonians are more Convenient for Deep sky observing and schmidt are for both deep sky observing and high mag! Planets and moon! But both fair equally. But schmidt cassegrains can get higher mag easily!
Edsan91 2 years ago
Brightness depends only on aperture. A 10" SCT should have the same light gathering power as a 10" reflector. However a 10" SCT although a shorter tube probably weighs as much if not more than a 10" reflector tube. The longer FL means a more narrow FOV. A dobsonian with a f/5 will have a much bigger FOV than an f /10 SCT.
