The Ghost Nebula | Full Tutorial

In this video I'll show you how to find, photograph, and edit the Ghost Nebula (Sh2-136). This is a very challenging target, so it helps to shoot from a dark sky and capture 15+ hours of data. You'll also want at least 1,000mm focal length, that way you can resolve the finer details.
