NGC 7822

 My last post for NGC 7822, a star forming region in the constellation of Cepheus, was on October 26 of this year. The image I posted was a short integration of 33 x 45 second subs (a total of about 25 minutes). The resulting image needed significant noise reduction in Topaz DeNoise, but the result was worthwhile. Last night, I decided to add to this data. Before clouds rolled in, I was able to capture an additional 200 subs. The image below is a stack of 233 x 45 second integrations, for a total integration time of about 3 hours. The result shows a much better contrast balance and more detail in the surrounding nebula. Click and zoom for more detail. The second image is a crop of the core region of the nebula, showing its "Pillars of Creation" features.

Tech card: RASA 8, NBZ filter, DS10C camera. 233 x 45 second integrations.
