Cygnus is one of my favorite constellations for astrophotography.
It contains many deep sky objects but one of the most spectacular is the Veil Nebula, a large but faint supernova remnant.
This is my attempt to capture the western part of it, which is known as The Witch's Broom.
I have used Ha light to reveal the nebula details and I hope next time to try with OIII also.
