This is an advanced request I did where I got some weird reflections, so I tried again and got some weird reflections, so I gave up and processed with I had. It turned out decent. 3x L, 3x R, 6x G and 5x B, all 600s.

Sad about those weird reflections. Are they in all the color channels? Adam Block has a good tutorial on YouTube. It helpt me a couple of times.

Not in all of them, but they are bad enough that the cost of the subs were refunded and the second set wasn't charged.

I have actually created a tutorial on the FB group that shows how to take out dust spots, reflections, and vignetting, so basically false flats that also kill reflections, but these were bad enough to clip the highlights. Here it is https://imgur.com/cWim6Qz

Yep, and it hit again on CHI-4 when I tried to redo them. I imagine it has something to do with the position of the scope at a certain time while imaging, and that certain time is going to be either when the object sets or later in the season. Basically has to be when the scope is pointed in one certain direction, and it is both CHI-2 and CHI-4, so there has to be something common between the two. I would almost bet that it will come down to the position of the corrector, focuser, and some kind of light being picked up while aimed in a certain way.
