Yeah, I think this is a combination of factors really. I will be cleaning my corrector plate with Eclipse solution and pec-pads, I will be doing a manual focus with a bahtinov mask, I will then use a dew shield to capture lights and then, I will finally take fresh flats.
If, after all of that I still get this halo, it's gotta be light pollution and I'll be selling my scope
