Description

Sh2-198 is the small nebula towards the bottom of my frame and is usually imaged with Sh2-199, which is much larger and considered a famous object to image (The Soul Nebula). Sh2-198 is somewhat dim but responds very well to Ha and makes a great black and white image. I wanted to take it to the next level and capture in in SHO. There is some SII, which I had to push very hard, but no OIII.
