Title: Crescent nebula NGC6888
Post by: Carole on Dec 24, 2019, 12:35:56
This is "sort of" a reprocess from November 2018, except I didn't use the full frame at that time, so this is the first full frame process.  I think I cropped it because I wasn't happy with the corner stars, and wasn't all that pleased with my processing of the outer nebulosity, so decided to give it another "go". 

Ha 12 x 600
Oiii 7 x 300 binned
RGB stars R x 3, B x 4, G x 4 (all 150secs binned)

Atik460EX & WOZS71 + FR x 0.8 HEQ5
