Best way to see Andromeda galaxy

Click For Summary
SUMMARY

The best way to observe the Andromeda Galaxy (M31) using the Orion SkyQuest XT8 PLUS Dobsonian Reflector Telescope is to utilize the Orion 2" 28mm DeepView eyepiece for a wider field of view and optimal light collection. The 10mm Sirius Plossl eyepiece, while offering higher magnification, is not recommended due to the galaxy's large size. Observers should also explore the Orion Nebula and other bright celestial objects, particularly in dark-sky locations. For beginners, resources like "A Field Guide to the Stars and Planets" and Sky and Telescope magazine are invaluable for enhancing the stargazing experience.

PREREQUISITES
  • Understanding of telescope types, specifically Dobsonian reflectors
  • Familiarity with eyepiece specifications and their impact on viewing
  • Knowledge of celestial objects, particularly the Andromeda Galaxy and Orion Nebula
  • Basic principles of light collection and magnification calculations
NEXT STEPS
  • Research the Orion 2" 28mm DeepView eyepiece specifications and benefits
  • Learn about the Orion Nebula and other notable celestial objects visible from New England
  • Explore light pollution reduction techniques for optimal stargazing
  • Read "A Field Guide to the Stars and Planets" for beginner astronomy insights
USEFUL FOR

Astronomy enthusiasts, beginner telescope users, and anyone interested in observing celestial objects like the Andromeda Galaxy and Orion Nebula.

I just recently got a dobsonian reflector telescope, (Orion SkyQuest XT8 PLUS Dobsonian Reflector Telescope) and I was wondering what the best way to see the andromeda galaxy would be using the telescope? Of these, which would be the best eye piece for that sort of thing?:

Orion 2" 28mm DeepView telescope eyepiece
Orion 1.25" 10mm Sirius Plossl telescope eyepiece
Orion 1.25" Shorty 2x Barlow

Also, if not the andromeda galaxy, what else would be able to see that is especially neat to look at with this kind of telescope? I live in the new england area, if that helps. Any tips would be greatly appreciated, I'm just starting out so I need all the help I can get. Thanks!

For a galaxy, you want the least magnification/widest field of view you can get. So that would be the 10mm eyepiece.

You'll definitely also want to look at the planets, the moon and some of the brighter nebulae (Orion Nebula to start).

To build on Russ' answer, M31 is big. Really big. Bigger than the moon. You don't need magnification - it will only mean you'll see less of it. You need light collection, and you'll want to go where the sky is darkest.

Russ is right about using the least magnification. But that would be with the 28mm eyepiece. Magnification is scope focal length divided by eyepiece focal length.
In your case 1200/28 at 43 vs 1200/10 at 120.

The New England area? I heard that all you can see there is clouds. Come to Arizona for a real sky. :-p
If you go out after about 9-10 pm, Orion should be coming up in the East. The Orion Nebula is a beauty to look at.

There exists in the Petersen's series "A Field Guide to the Stars and Planets"
that i found very helpful getting started with my first telescope, a short little 4.5 inch reflector.

Also Sky and Telescope magazine i found fascinating. Check out their weekly sky guide at
