Taken on 14 Sep but I've only just got round to processing it.
Modified Sony A7S on Tak Epsilon 180ED. 140minutes of exposure in 30sec subs at ISO 10000.
Very quickly processing in PixInsight & Photoshop as follows:
Stacked
Degree 1 AutoBackground Subtraction
Arcsinh Stretch (stretch factor x90)
Slight colour saturation of everything except red
Noise reduction in Photoshop

what can I say Mark - crap as usual.. I'd give up on this hobby if I was you. btw just set 'crap' as my new windows background ;-)
Stunning...
Lovely rendition Mark. Much wider FOV than my recent one which l did in NB. Looks so different in B.B. beautiful star colours as usual.
