Description

A reboot with new data of a target I have previously looked at.

The previous target was pretty but I felt it lacked all the detail the target had to offer so added an additional 30 HA subs from the RH to help realise that. Small percentages but makes a lot of difference when reviewed in detail.

It also allowed me to resolve the ICC mismatch issues my PC suffered after recent updates which caused all sorts of issues on my last image!

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.
