Description

A most unusual planetary nebula, with a diameter of about 2 degrees. Sh2-216 is probably our closest known planetary nebula, around 400 ly from Earth. It is also one of the oldest known. The object is extremely faint, and was very difficult to process. A dark sky would probably help, or very narrow filters.
