OK, I am not all that unhappy with this, in my continued skill development. One step forward, two steps back.

 

But, what in the world is the band running through the bottom of this pic, and can it be processed out?

 

Additionally, if you blow up the exposure, there is a very dark area just to the left of the Rosette. Is that something on either my filter or scope?

 

Lastly, this was a cropped image, and to the right, still you can see the glow. Amp glow I would assume?

No flattener/reducer (ditched it to see if I could get better stars, which is counterintuitive, but the 61R has given me FITS

1. That is not amp glow. It's a gradient.

2. Blink your subs to find the one(s) that are causing this band. Then, either change your pixel rejection parameters or dump these subs.
