Great result and wonderful image from all that hard earned data
Astrobin really does it justice
Well done indeed !!

PS: I’m glad I’m not the only imager that has used Bias to calibrate Flats. I’ve been advised both here and on other forums to use Flat Darks in lieu of Bias as best practice to ensure any dark current is calibrated out of the Flat. So I’m using Flat Darks now. For the life of me I can’t tell the difference between Bias and Flat Darks ( even down to pixel level ) as I’ve compared a few different broadband and narrowband images taken from both Bortle 8 and Bortle 3 skies. My Flats are usually 0.1 sec to 0.5 sec for Broadband and 1 sec to 5 sec for Narrowband ( I take 40 Flats ) and I suspect that the resultant dark current would be extremely low. I’m sure the Bias comments relate to other CMOS cameras , not the 2600MM ( super low noise high QE camera )
I’m still going to keep use Flat Darks !!
