SH2-4 (Sharpless 4 ) This small and bright nebula has some interesting structure around the brighter area that a large telescope. The nebula has some brighter areas around it that allow the wide field telescopes to pick up some interesting nebulae in the area. The nebula does well with the hydrogen-alpha and the red filter. There was very little blue and green that picked up so the region is quite a bit on the red site. For a complete list of the Sharpless Catalog visit my main site at http://www.sharplesscatalog.com
