SH2-278
Sh2-278 is an emission nebula in the constellation Orion. It is observed in the western part of the constellation, about 3 ° west of the Orion Nebula and 3 ° NNE of the bright star Rigel, the brightest of Orion. It can be easily photographed through a medium power amateur telescope equipped with special filters, even if long poses are necessary. It is a fragment of the gas clouds that make up the molecular nebulous complex of Orion. Basically, the nebula is made up of two comet-like gas canopies. Part of the gas that makes up the cloud is not ionized, thus remaining dark, while other parts are instead illuminated but not ionized, thus shining by reflection.
