Veil Nebula Complex
The Veil nebula is a large, relatively faint, supernova remnant in the constellation of Cygnus. At an estimated distance of 1470 light years the nebula is formed of a cloud of ionised hydrogen and oxygen gas. The star that formed the nebula is thought to have exploded between 5000 and 8000 years ago and the matter from that explosion has been expanding ever since to cover an area of roughly three degrees, or six time the apparent diameter of the full moon.
The final image is made up of a four panel mosaic and the raw data was gathered over several sessions throughout the Autumn months of 2016 and 2017. Shot in narrowband Ha and OIII wavelengths, with RGB added for the star colours, the total exposure time was just over 30 hours.
Location: West Midlands, UK
Scope: Tak BabyQ @f/3.9
Camera: Atik 460EX, Baader Ha, OIII and RGB filters
Mount: SW AZ-EQ6-GT, OAG
Total integration:
80 x 600s each for Ha and OIII, 72 x 60s each for RGB
Acquisition: SGP
Processing: PI and Photoshop
