Worth messing with...or chunk in the trash.
First attempt at stacking much with APP. I haven't even tried anything with it in PixInSight yet. This was over 2 nights, and I think that is why there is a line at the top and bottom (probably from alignment since some were after a flip) that cropping can take out.

Looks all right. Did you focus after a filter change? BTW what make of Narrow Band (NB) filters are you using?

I have SM set to auto-focus after each filter change, and it seems to work.
The filters are the "Premium" ZWO LRGB 1.25" and the ZWO Narrowband SHO 7nm threaded for the ZWO auto-focuser.
