Awesome work! Im trying to do the same sub-$1000 astrophotography with much less success. I spent half on the telescope (Celestron Nexstar SLT 130) hoping I could use my cell phone for imaging but looks like I should have saved more for the camera. Didnt work out so well so far but I think an inexpensive eyepiece camera and stacking will solve the remaining issues. Keep it up... this hobby doesnt have to break the bank to open up the cosmos.
