Those through-the-eyepiece cell phone shots are fantastic! My attempts at the same resulted in utter failure
I used this super cheesy phone-to-scope adapter as an aide. By no means does it make it easy, as I still have to support/hold and mess with the phone a lot but it does make it a little bit more possible to align with the eyepiece.
Switching to the fun bruiser, knock arounder Sharkmaster 600...YaY!
