Hot, young stars and cosmic clouds of gas and dust seem to crowd into NGC 7822. The image includes data from narrowband filters, mapping emission from atomic oxygen, hydrogen, and sulfur into visible colors and their combination is somewhat subjective, thereby making it a false color image. The atomic emission is powered by energetic radiation from the central hot stars.
This glowing star forming region lies about 3,000 light-years away in the northern constellation Cepheus and the section shown here is approx. 8 light years wide.
Even though this nebula has no formal name, I see a horse (left) and a cow (right) in this nebula, so I am naming it Cow & Horse Nebula!
This picture was taken in Hydrogen Alpha (17 images of 20 minutes), Oxygen III (11 images of 20 minutes) & Sulphur (18 images of 20 minutes) making it a total of 15.3 hours of imaging. The image was cropped by about 30% on one axis.
