I finally took my rig outside and now the issue is gone. How? I have no clue but its definitely gone. I haven't done anything except cleaning the lens, the camera sensor and the reducer.
Anyway, now my small stars have tiny rings inside, what the hell is happening every time i go outside there is a brand new problem to solve
Please see attached pictures, they haven't been modified just autostretch in pi. Everything else looks in focus, can this be collimation issue? I was using optolong l-enhance if it makes any diff.
