A part of the Veil nebula complex from Cygnus. This is Pickering’s triangle and Witch’s broom (NGC6960). This supernova remnant glows in Halpha and Oiii frequencies which is perfect for LeXtreme narrowband filter that selects those frequencies. I have tried this image several times before but this 4 hour exposure is the best so far. There is so much detail and color of the nebula that I couldn’t capture before.

Interestingly, the bright star near Witch’s broom, 52 Cygni is at 290 light years while the veil nebula is at almost 8 times that distance at 2400 light years. This supernova happened between 10,000 and 20,000 years ago. Anyone looking at the sky at that time probably saw a star much brighter than Venus.
