SH2-198 (Sharpless 198 ) This small nebula usually is imaged with Sh2-199 which is much larger and considered a famous object to image. The nebula is somewhat dim but responds very well to hydrogen-alpha and makes a great black and white image. The nebula is fairly dim with the color so using the H-Alpha image helps colorized the object. For a complete list of the Sharpless Catalog visit my main site at http://www.sharplesscatalog.com
