NGC 7822, also containing Sharpless 2-171, is a star forming complex in Cepheus. It is
located at a distance of about 3,000 light years. Interesting forms can be seen in the dark
areas which are caused by the powerful solar winds from the hot young stars, which
sculpt and erode the clouds of gas and cause them to glow.
