NGC 7822 aka SH2-171 is an irregular emission nebula in the
constellation Cepheus. Other than providing data for the star
colors, the green and blue filtered data didn't add much to the
image. The region is mostly hydrogen, which was captured with the Hα
filter and mapped to the red channel. This gives a result that is
fairly close to a true RGB image.
