Description

"Sh 2-161 is a large diffuse nebula surrounding the much smaller (and better studied) Sh 2-158/NGC 7538.

The BFS catalog argues that Sh 2-161 is actually two distinct nebulae in the same line of sight, which they designate Sh 2-161a and Sh 2-161b. (Sharpless himself made no such distinction.) "
