M83 redone....

Greg,

Thanks for the tip - I have been meaning to get into layer marks and selective application of sharp/blurr/noise reduction etc Attached is my attempt at this styple of prcessing - I think the result is better but I have so much to learn with this technique - there are just so many variables it is hard to know what to do for a best result.

BTW I am still having a few issues with my flats - even after re-doing them some of the darkest bunnies are not removed by calibration. I used the T-shirt technique early this am - I folded 4 layrs to avoid having to use very short exposures - so the flats were at 0.2s.

Attached is a new M83 and a sample flat, is this typical or am I in trouble with this much gunk on my sensor?
