M31 - Andromeda Galaxy through a 6 inches refractor

[galaxy31M]

I now feel very small... Again.... This is amazing.

[SeanKimStyle]

Also at what magnification could you view andromeda galaxy like this?

[SeanKimStyle]

Achromat refractor? I'm thinking if I should buy 6" instead of 5" (Explore Scientific). How much difference in between 6 and 5?

[xFruitsBasket]

Its pretty amazing to see another entire galaxy with a telescope.

[markuslebt]

she is so close isnt she....

[joikbenik]

@markuslebt like 2.5 million lightyears away, i think andromeda galaxy is the closest galaxy to our milky way galaxy

[markuslebt]

@joikbenik i just got m toUcam 840K today now i need to make long exposure modification after that i´m gonna try use my equatorial mount and 10inch dobson to get some decent pictures. the mod looks kinda complicated however..

[joikbenik]

cool :O

[gnupuppy]

Amazing video for a six inch scope. Thank you for sharing.

Question: when your viewing these deep sky objects like nebulae and galaxies, will you see the clouds in them? Or is this only when you take the pictures? When I view the Orion nebula, i can see the clouds of gas in it but when i view something fainter like the dumbbell nebula i cant see the clouds.. is this normal? Also can you attach eyepieces and filters when doing astrophotography or is it only through the camera with no additional help (like how eyepieces can make you see closer up)

[BrAdEnSB666]

I CANT FIND IT. ITS SO HARD TO FIND!

[denispkpk]

@BrAdEnSB666 It's incredibly easy to find.If you really can't find it then go to:

/watch?v=DD3Nxu-RbvM

[keven444]

@BrAdEnSB666 try to find it with binoculars before telescope its way much easy :P

[Neueregel]

Why 30 seconds? 20 second-exposure might have resulted in a less blurry image

[m4n52k10]

that was cool will i be able to see this through a celestron powerseeker 127 eq

[stopdown555]

This is quite a good effort, I like the pinpoint star images. I am a proponant of refractors, and always get the urge to stop them down to maximise performance. Modest apertures are rewarded by having to contend with fewer atmospheric platelets.

[frostyuk2007]

What is the best camera for recording deep sky?

[madcram]

Wow, I'm lucky just to see a blob of light where I live. Nice job :D.

[azzy314159]

I am planning to take my Vixen 130SF and a GP2 mount up on top of the hill (at 8200 feet plus) next to my home There are a few lights at the top and a couple of comm towers with red lights but my concern is my small town down below me at 4200 feet and about 5 miles as the crow flies and visible. Will the city influence my view. Its a complicated to arrange and I am worried it might be fruitless. Wondering if it is worth the effort or should go further away from the city?

[CumputerPhysiscsLab]

@azzy314159 Probably it is a better idea to go visual naked eye a first time to the summit and check the quality of the sky there. If you see a lot of stars without telescope it means the quality for deep sky observation is good.

[azzy314159]

@CumputerPhysiscsLab Thanks CPL. I think I will make a foray before I take the star party out. I have noticed that on one night the sky was clear but the stars seemed to twinkle although very bright. Wondering if twinkling stars are better or worse for viewing ?

[CumputerPhysiscsLab]

@azzy314159 There are two things to take into account when looking for good night skies. First it is "seeing". Second is "light pollution". For deep sky observation, the key is avoiding light pollution. For lunar/planetary observation the key is to get good "seeing". Twinkling stars means bad seeing, bad skies for planetary. That is very usual on any summits in the world. Summits are good for deep sky observation. Shores are good for lunar/planetary.

[Napoleontas]

with my 130mm telescope i could barely see a blurry light of the andromeda ,is that normal?

[CumputerPhysiscsLab]

@Napoleontas Yes, that's normal. If you use a bigger telescope, you may see more details (but not too many more) like in this video. Dark skies are compulsory to see something more than a blurry spot.

[Napoleontas]

@CumputerPhysiscsLab I was in my village , i think that we have quite a dark sky, iam 40 klm away from any major city. Of course the village has some lights but i dont think that will make a great difference of course iam not so experienced.

Do you thinkt that a 10 inch in comparison with my own 5.1 inch ,will make a great difference, should i proceed with a bigger telescope?

Thanks in advance

[CumputerPhysiscsLab]

@Napoleontas Sure. It is different to see through a 10 inch than through a 5 inch telescope. A 10 inch will show you a lot of galaxies, meanwhile a 5 inch only shows the brightests like M31.

[Napoleontas]

@CumputerPhysiscsLab Thank you , i will try to get into some star "parties" and watch from their own telescopes what is visible, then i will decide if i'll get a 10 inch , money is the only problem here.

[Kapseros]

@Napoleontas You'll definitely get a difference. The general "rule" says every buy of next telescope to be +4 inches compared to your previous one. If you had a 6 inch reflector I'd suggest a 10 inch. A 10 inch telescope can collect hundreds more light than an 6 inch. You're very lucky staying in a place with no light pollutions. Go for it. ;)

Greetings from Athens, Greece

ps Napoleontas? Where you from? :)

[Napoleontas]

@Kapseros Thank you friend!

I am from northern Greece thessaloniki

[azzy314159]

@Kapseros A 10 inch telescope can not quote "collect hundreds more light than a 6 inch" unquote. It collects exacly 2.78 times more light.  Get your facts right, Mr ass-tronomer!

[Kapseros]

@azzy314159 Thanks for your sweet comment. Not my fault if you had ...rough times in school mate. ;) To be accurate a 10'' inch telescope can collect 56% more light than an 8 inch, while an 8 inch has approximately x4 light collecting capability than a 4 inch. The difference in the eye seems much greater, but it is definitely not "hundreds of times more", as I wrote below.

[mrastronomy15]

That is one nice galaxy, to bad its not augest yet, I'd be able to view it. Nice work. Keep it up.

[turtle5181]

very nice

[rohannat]

What is the other really Bright Spot between 3 and 4  O'clock?

[CumputerPhysiscsLab]

@rohannat It is M32, a small galaxy orbiting M31.

[daddyschlong14]

@CumputerPhysiscsLab I was just about to ask the same thing, that's awesome! Hopefully I will be seeing it tonight.

[achimreinhardt]

Schöne Aufnahme!

What Kamera ?

Danke

Achim

[CumputerPhysiscsLab]

@achimreinhardt Canon EOS 450d, Rebel XSi.

[istvanklein]

It's astonishing to know that you look back 2.5 million years in time when looking at Andromeda.

[Edsan91]

Really? wow still looks good!

[Edsan91]

Very Nice! And Wow Very Excellent sharp quality! The optics must be Superb on that Refractor!

[CumputerPhysiscsLab]

@Edsan91 Actually it is not apochromatic, so the blue channel is giving me to much headhaches ...
