Sh2-301 or Gum 5

Is an emission nebula in the constellation of Canis Major. This spectacle rich in Oxygen, Hydrogen and Sulfur emissions is often overlooked as it’s close to Thor’s Helmet and the Vela super nova remnant. It has a lot of structure as well, many small columns of dust and gas, wispy blue areas of oxygen and a nice Bok globule in the center.

This is one of the most detailed amateur photographs of this object to date. Overall, a very good target for a large amateur telescope.
