Video tutorial on how to record through telescope w/webcam

[rfnking11]

you my friend have just saved me about £90 so thank you very much indeed!!!!!!!!!! :)

[Luisonsky]

I see that my comment is not published about your video tutorial, but said I did the same with my mobile phone camera with good results, as seen in the video of jupiter I'm now inquiring ways to increase the magnification of the observations.

[Edsan91]

@Luisonsky I see I see! Very nice! :D but with your mobile camera!? Wow nice :)

[fastestcars2011]

does it appear pinkish

[Edsan91]

@fastestcars2011 If you mean that if the webcam appears pinkish after removing the lens from the main CCD part yes! It will appear a weird pinkish color because mostly most cameras have a small film over the main CCD or CMOS Sensor making light appear pinkish after removing the lens. That small film(ir cut filter) a long with several other films helps the camera better gain light and filter some of the colors to the sensor. If you mean something else...Maybe its the settings on the program.

[fastestcars2011]

@Edsan91 the image comes out pink ive fiddled around with all the settings but it just

staying the same is it because its in daylight .

[Edsan91]

@fastestcars2011 Have you put it on the telescope and focused the focusing knob? And in daylight yes it would appear more pinkish. But try putting the webcam on your telescope and focusing it. How do you have the webcam setup?

[fastestcars2011]

@Edsan91 yes ive done exactly what you do in your video and put the webcam right on the the focusing tube ive focused it and i can see a good image but its pink for some reason.

[Edsan91]

@fastestcars2011 Are you using it during the day? If so try it in the night on the moon a planetary object because I think maybe its too much sunlight entering the webcam that is making it pink! What are you trying to capture with it?

[Edsan91]

@fastestcars2011 Otherwise in the settings play around with the "Custom White Balance" Settings or something similar like that to get your desired image!

[Echo4nineteen]

We do share the same interest though.

Clear skies to you :0)

[Edsan91]

@Echo4nineteen :) Yup! Clear skies to you too! :D

[Echo4nineteen]

I like the tutorial, thanks for posting...

I had to mute it though.

[Edsan91]

@Echo4nineteen LOL I wonder why everyone hates that music XP hmmmm I will remove this video then and re upload again but with no music lol

[Edsan91]

@Echo4nineteen And thanks for watching!! I hoped it helped! I had fun making it.

[Salonan34]

good useful video, dont matter what kind of music, people just love to complain, anyway thanks man for the great info.

[eggbertsmith]

MUSIC FAIL!

[weasele1]

holey cow i muted to

[Edsan91]

@weasele1 OK lol the video is coming down XD or the audio Ill try.

[LEGENDPURGE]

@Edsan91 Hi Edsan91, what webcam is that?

[Edsan91]

@LEGENDPURGE I do not know the brand because it is a really really cheap 10$ webcam off ebay. Just search for" webcam" on ebay and this similar webcam will appear! It is very cheap however! Mine already broke and needs to be repaired and re soldered. But for the price and if taken cared of well I think its ok. Sorry for my response a little late I have been busy with other things.

[Anvilcjl]

Without an eyepiece on the camera the image is very small compared to what the scope is pulling in, it's magnified way in, small field of view. With the lense and eyepiece projection I see something closer to what I see with my eye... How do I fix?



[Edsan91]

@Anvilcjl Yes that is true! Because the focal length of the webcam is at about 4mm or 3mm it is like using a high powered eyepiece. A simple fix is buying a "Focal Reducer" Which will reduce the FOV/ratio/length of the telescope and make it wider than narrower. Therefore making it more zoomed out and close to how your eye can see. Usually when viewing objects with a webcam its meant for planetary and the Moon. But to see it closer to what your eye can see. A "Focal Reducer" is a must buy!

[Anvilcjl]

@Edsan91 Thanks

[polarpol]

hi!very useful tutorial.i've got a little problem though.i've done just like you showed but when im trying to film moon its all shaky and blurry.cant figure why:(.do you know why?btw...i'm using ETX 125.Thanks!

[Edsan91]

@polarpol Thank you very much :), A webcam to telescope adapter would help! But also check to see if you have your telescope foucuser focused right. Maybe you just need to turn it a little bit more :)

[Edsan91]

LOL why does everyone hate the music XD if there's anymore hate Ima redo the video if I find those old videos on my computer but this time wit NO music. If I don't find them....then just mute the video! But still if anymore hates on the music I'ma take it down. Maybe redo it in HD quality next time.

[NocturalRyte]

Thumbs up if you had to mute the audio to get through watching the video.

[Edsan91]

@redmatrice hehe XD lol :) I'm glad to have shared this video! And I hope it has helped many people!. I wonder why many people don't like the music tho lol.

[redmatrice]

@Edsan91 i still didn't try your tuto, but it looks very helpfull, ty

music is like food, you can enjoy eating a pizza but you'll find too many people who will find it disgusting

[redmatrice]

@Edsan91 your tutos looks very helpfull, didn't try it yet :)

music is like food, you can enjoy eating a pizza but you'll find someone who will tell you "how can you eat that? it's disgusting!!"

lol so just eat what you want ;)

[Edsan91]

@redmatrice lol haha yup

[cheddarbounce2]

so does the webcam lens decrease magnification?

[Edsan91]

@cheddarbounce2 I think it just sees it how the eye would see. Idk Yet I haven't tried it but I think so.

[cheddarbounce2]

Oh and i dont understand. is 1000mm focal length too much or too little

[Edsan91]

@cheddarbounce2 It is ok! Its not too much and not too little. To put it in simple terms the more focal length you have the more you can zoom in or magnify on objects closer. The less focal length you have and the less you can zoom in on objects. Less focal length is great for wide field shots. More is perfect for planetary and Lunar observations also for some very far away galaxies.

[Edsan91]

@cheddarbounce2 Say this is 500mm focal length ..... And now say this is 3910mm focal length........................­................ You will get wide field views in the 500mm and less zoomed out. And very close and zoomed in on the 3910mm one.

[Edsan91]

@cheddarbounce2 I know its a bit hard to understand. I didn't get it at first but I learned it and it made sense. I might make a video of it to explain it.

[cheddarbounce2]

I returned it.........but im thinking on buying a 12M pixel led webcam from ebay. infact its the one your using on your video

[cheddarbounce2]

I decided to use a webcam so I bought one. When I put it in the focus rack, all I can see is the secondary mirror with the primary mirror reflection. ( It is a 114mm/1000 Newt reflector) I then heard to insert a 2x barlow lens, so I did.....this made the mirrors look zoomed out even more than before. What shall i do ? Can someone recomed help to me? and recomend a good/decent not too fancy webcam under £15.

[Edsan91]

@cheddarbounce2 The lens is still on so you would need to take off the lens hehe yes thats what a barlow lens does its a negative lens so it makes the focal length longer. What kind of webcam do you have? And also you can try putting an eyepiece on your telescope first, and then you put the webcam on top of the eyepiece and it'll work! That's easier. The thing you are missing tho is taking off the lens on the cam if you take it off the mirrors Won't look zoomed out more.

[Edsan91]

@cheddarbounce2 But be very careful! You can scratch your eyepieces that way. That is why I prefer this method instead. What cam do you have? You will need to disassemble and modify the webcam to be useful :) its a bit hard but its worth it. A logitech maybe? or A philips toucam also works also u can get an webcam adapter it makes things so easy!.

[Astrofreack]

Thank you for this video! I haven been looking for a tutorial how to make a webcam good for filming through a telescope. At the moment I'm strugling with my iphone because it auto focus all the time. Do I need a webcam without auto focus or can I take any webcam?

[Edsan91]

@Astrofreack Hi Astrofreack :) any webcam works if its used without its main lens. The the only part is to expose the CCD of the webcam and put the sensor on the telescope. In other words the little lens I removed in the beginning of the video is the webcam lens, without that it won't autofocus. The Telescopes Focusing knob will become its new focusing. The little lens is what makes the webcam focus. Now with the telescope it becomes a Super Telescopic Webcam working at high magnifications.

[Fam2014Ch]

better without the music... Nice video.

[Lekkerie]

Great tutorial, thanks. I have the same cam :]

[AndyFlash0f]

i have the same camera and those leds wont switch off!!!

[Edsan91]

@AndyFlash0f LOL theres a small slider thing that switches them off tho if it still doesn't switch off then its broken lol. At least u can see in the dark with them on :D

[AndyFlash0f]

@AndyFlash0f broken

[hallobaaaby]

Thanks for the vid! i think that if you want higher magnification with the eyepiece you should do it with the cam's own optics on.

[zaye525]

thanks

[ParaglidingManiac]

Hello friend,

help! my camera won't support manual exposure control. autoexposure is driving me crazy!:( anything you can advice me please?

[SaturnAndItsRings]

this was highly helpful it is really what I needed

[krisDM3000]

Great tutorial, very clear and easy to follow. Thanks : )

Now all I need is a laptop and a webcam. hmmm.... d'oh. Don't have that lol : P

But maybe in the future I will.

[NCAstronut]

Thanks for this tutorial. Kinda wish I had keept my filter that was on the back side of the lens. With out this the image is black and white. I lost the filter part. :(

[Edsan91]

@NCAstronut Yea man Your welcome! :) Thank you for watching my friend :) And thanks for adding it as a favorite :D It means alot to me thanks :)

[NCAstronut]

@Edsan91 I have not had a chance to try my webcam out yet. Do you know right off if I'll still get images in color with out the IR Filter in place? I lost it. Thanks. Nice scopes man.

[Edsan91]

@NCAstronut idk what kind of webcam u have but as long as u have a ccd (the square thing) u should see an image. In color i don't know :( IR filter? Is it one of those special cameras that can see like in night vision? Awesome :D if you take of the Ir filter and shows no color ur best bet would be by putting an eyepiece first and then ur webcam on top. Just try it :) and see how it goes! oh :( Maybe u can buy it on ebay craiglist or somewhere? Thanks man! though I just sold the black one ;)

[NCAstronut]

@Edsan91 O yeah minbe is a logitec quickcam 2500 E. It's just a basic webcam. I'll be looking at getting a better one to mod, this time I'll leave the IR Filter in. And just remove the lens. Thanks.

[Edsan91]

@NCAstronut ah I see nice webcam :) Better than the one I have! Cool then! I recommend an HD one if u can get one :) But whatever cam nowadays is good enough :) Your welcome my friend!

[xXRACERXx88]

Ha ha the basic point is to take off the lense and attatch it and I don't have a lens. But thx anyways 5/5.

[Edsan91]

@xXRACERXx88 Yup! I should've gotten to the point? lol or this video is ok? Thanks for watching! And rating as well!

[PrognatusSeptem]

Hi,

We just got a polaris eq-d and want to take video...thanks for the tip

[chriskeliris]

Fantastic! i will have to give this a go and some point, i would love to try and use this technique on Saturn!

[ParaglidingManiac]

Very very good! You won't find anythign similar to this on the web! At least I didn't succeed in this. Great tutorial, thank you!

[Edsan91]

Thanks man! I enjoyed making it!

[UltimategamerXFX2]

GREAT video! I hope i will get a telescope someday! and then im gonna record...just like this.... xD

[xXMarco14Xx]

Great vid, 5/5
