NGC 2736, also known as Herschel's Ray, is actually part of the Vela Spurenova Remnent, a huge complex weave of nebulosity encompasing most of the constellation of Vela. Several of the filaments in this expanding shell of gas are bright enough to be visible to the eye in the telescope. NGC 2736 is one of those filaments. It is easily visible in a 12" telescope.
