NGC 6960 - Witch's Broom Nebula with processing pushed to limit
The Witches Broom Nebula is the western part of the large Veil nebula complex. It is the remnants of a star the exploded ten thousand years ago in the constellation of Cygnus. The colors you see are the result of two processes of stars interaction with the gas left over from the explosion. The Blue light happens when light from a nearby star reflects off the gas like a mirror. The red light happens when light is absorbed by hydrogen gas and then re-emitted. This nebula shows both kinds and is a great example of both. 30 x 500 sec exposures 9.25 SCT @ f/6.3 ASGT Mount Q453-HR Camera ST80 guided using DSI Pro PHD/Nebulosity Deep Sky Stack
