I recently bought CELESTRON PowerSeeker 127EQ Telescope  and found the following video very informative and short for quick setup

I tried to set it up and take few pictures by just placing my small digital camera (Nikon 3200) and result was better than expected

However I think buying a digital eyepiece  would help everything capturing in a computer digitally.
Other way is to use Universal Digital Camera Adapter for Astrophotography.
I will keep updating my notes as I keep reading and discovering  more information.
