      Description

      This was a nice target to work with - nice complexes in the main nebula offset with fine background nebulosity and details. The weather curtailed further data collection as normal so went with what I had.

      Also liked the stars and Berkeley 59 is this target.

      Rev A - Main Version (My preference)

      Rev B - Background lifted a little (Some have expressed preference for this one - I will let you decide as very subtle)

      Rev C - Testing AB's new ICC profile feature only (same version as B)

      Rev D - Saved to AdobeRGB ICC profile, this seems to present better across all my devices. Some of you, especially those on mobile devices may have previously seen a burnt out area at bottom of nebula. This AB update and the use of Adobe RGB seems to provide consistent viewing experience across the devices I have access to (from fully calibrated monitor to mobile phone). Hope this is of help to some of you.

      Oh, and unless we have a sudden change to excellent weather this is my last image from this location before I move house so might be a while before I am producing my own data again

      NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800-1000 pc distant, with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45000 K and a luminosity ~100000 times that of the Sun.
