Title: Ced214 with NGC7822 in Cepheus
Post by: MarkS on Oct 23, 2017, 23:55:33
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

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.
