IC 2177 Seagull Nebula
There is a 2020 version of IC 2177 HERE
IC 2177 is a region of nebulosity that lies along the border between the constellations Monoceros and Canis Major. It is a roughly circular H II region centred on the Be star HD 53367. This nebula was discovered by Welsh amateur astronomer Isaac Roberts and was described by him as, "pretty bright, extremely large, irregularly round, very diffuse."
The name Seagull Nebula is sometimes applied by amateur astronomers to this emission region, although it more properly includes the neighbouring regions of star clusters, dust clouds and reflection nebulae. ....a much larger FoV is required to get the full seagull.
