Hi Vijay,
1) I use an app with my iPad called SkySafari -
http://skysafariastronomy.com/. Best thing I ever did! With a little patience I can find almost anything
, I run an older version, SkySafari 3 Plus, however the newer ones look even better and well worth the price (PS. I have no affiliation etc).
2) I suggest considering the use of an eye-patch to cover one of your eyes (unless of course you're using a bino-viewer). I found the eye-patch made things a lot more relaxing and enabled me to see things more clearly.
3) When you do see the galaxy, in many instances you'll see a fuzzy cloud. To see more, you'll need to use "averted vision" -
https://en.wikipedia.org/wiki/Averted_vision. Pretty easy to do and once you get the hang of it things will really start to pop out.
4) and finally, unfortunately galaxies are pretty faint so there's not a great deal to see sadly. Don't be discouraged though. I started doing observing and gradually moved into astrophotography, it's made a huge difference! Even just a camera on a tripod with 30 sec exposure can show you so much
. You can also get small adapters that connect to your eyepiece and allow an iPhone etc. to capture objects. Even with a 10sec image, you'll see quite a bit
Cheers, Evan
