Description

A portion of the Carina Nebula is known as the Keyhole Nebula, a name given to it by John Herschel in the 19th century. The Keyhole Nebula is actually a much smaller and darker cloud of cold molecules and dust, containing bright filaments of hot, fluorescing gas, silhouetted against the much brighter background nebula. The diameter of the Keyhole structure is approximately 7 light years.

This image is a 20x10 minutes stack captured using a GSO RC-8 and a CCD ST-8300C.

The autoguiding used a Lodestar CCD, Lumicon OAG and PHD.
