I recently got an AP rig for DSO imaging. I am an absolute beginner to AP, and photography in general. I think I have focus issues still. Rather than go down too many rabbit holes, I figured asking here was the best route first. I'm close...I think...
I'm working in ASIAIR and my stars have trails after not much exposure time. After my first 300s exposure, I realized the EAF was not on so I thought that was the trick. After turning on EAF, the images got way worse! I do have a Bahtinov mask, so I tried that again and was able to see the 3 spikes crossing correctly but the spikes were very small compared to other images I've seen online. They were also pretty far away from the star itself, if that matters. I was able to focus (I thought) and get plenty of detected stars around 2.2 in size. Any suggestions would be amazing!

This is all ZWO hardware paired with the Askar 71f, and W.O.'s newer 50/200 guide scope.
