The Sh2-202 nebula is a vast and faint emission nebula located on the border between the constellations of Cassiopeia and Camelopardalis (the Giraffe). This nebula lies in the vicinity of the star cluster Stock 23, also known as Pazmiño’s Cluster, which serves as a reference point for its location.
It is an H II region, where interstellar gas is ionized by the ultraviolet radiation of young, hot stars, giving it its characteristic reddish glow.
Due to its low surface brightness, observing Sh2-202 is a challenge that requires dark skies and large-aperture telescopes. However, for astrophotographers, it offers a unique opportunity to capture the subtle beauty of emission nebulae in less-explored regions of the night sky.
