Sh 2-312 is a nebula in the southern constellation of Pyxis. It is very large and diffuse, making it largely ignored and unstudied outside of its relation to the Gum Nebula. Sh 2-312 is located approximately 56 parsecs away from RCW 22,[2] another nebula postulated to be a part of the larger Gum Nebula,[3] which is itself estimated to be approximately 300 parsecs in width based on angular diameter approximation.[4][5] It responds well to Hydrogen-alpha filters; however, it requires extended exposure time to become visible during observation.[6]
