Thank you Andy,
I haven’t done a star removal as such but I have done a reduction that I always apply to my images. Essentially it reduces the brightness of the stars and tightens them up. Consequently when I apply noise reduction techniques, the most feint stars do get absorbed so in effect they are removed. The negative consequence of this is that it makes what is left more critical. I didn’t manually assess each sub but I did only stack the best 80%. There is a chance that something has snuck though. I’m contemplating adding some more hours ( weather permitting ) so if I do, maybe I’ll go though and be more critical in hope of a better result.
Bare in mind that the data used in this image was in bortle 8 skies with greater than 90% moon. Also with a known tilt issue that is amplified in f/4 optics. For anyone else considering going for a super fast scope, I can’t stress enough how sensitive they are,
Thank you again for your comments: they are really appreciated
