Exposure: 25×240″ @ ISO 1600
Telescope: Skywatcher Newton 8″ f5 with Baader MPCC
Filter: Hutech IDAS LPS 2″
Mount: Meade LXD-75 Autostar
Camera: Modded Canon 350D

Comments: Knowing so few about image processing, dealing with the gradients and the terrible background due to the light pollution was very difficult.

The above object is the west end of the Veil Nebula, also known as NGC 6960, but less formally as the Witch’s Broom Nebula. The rampaging gas gains its colors by impacting and exciting existing nearby gas. The supernova remnant lies about 1400 light-years away towards the constellation of Cygnus. This Witch’s Broom actually spans over three times the angular size of the full Moon. The bright star 52 Cygnus is visible with the unaided eye from a dark location but unrelated to the ancient supernova.
