Description

I had to try out NGC7822 again, this time with the RASA 8 (HOS) and Zenithstar 61 (RGB). Since I am back from vacay the skies stayed almost every night clear so that I got enough data together. This object is still not easy to process, and I am still not quite happy how it turned out, will probably reprocess it again one day.
