For what it’s worth Micheal, I think your efforts do show promise. No doubt imaging at over 1000mm focal length is hard but the lessons you can learn from trying to, especially with guiding can only make your shorter focal length imaging better. Learning how to fine tune things to get my guiding good enough for round stars with my C9.25 with 0.63 reducer ( 1530mm f/l ) gives me guiding on my 8” f/4 (800 mm) between 0.5 and 0.6 arc seconds. Pretty good I think on a HEQ5 pro with nearly 12kg of scope on it. It does take time though and I know a lot of the time you’d rather be using a clear sky for productive things rather than guide testing.
