I've been using the AP 160 for years visually and decided to try it for astrophotography. I wanted to try and capture a little larger image of some smaller DSO's and this seems to be a good combination of scope and camera for that.
30 minutes of luminance and red channels as a test, no calibration frames, just stacked and stretched.
