SH2-311 (Sharpless 311 ) This nebula offers a great deal for any size system. The wide field of view captures a very nice image of the nebula while large telescopes will bring out the very fine detail. The nebula does very well with the Hydrogen-Alpha filter and creating a color image is very easy to do. The nebula also responds very well with the other narrowband filters Sulfur II and Oxygen III to create a nice narrowband color image.
