Description

As a result of this deep image WeSb 2 is now confirmed in the HASH database as a true planetary nebula. It is in the constellation Auriga. It was discovered by Ronald Weinberger and Franco Sabbadin in 1981, but this is the first narrowband image, and first colour image, produced since its discovery. The nebula is approximately 3 arc minutes in size. It is very faint, which may explain why it hasn't been imaged before. The OIII signal was extremely faint.
