Description

NGC 6960 is the western Veil nebula, part of the larger Cygnus loop.  This image is an LRGB composite enhanced with H-alpha data.  The LRGB portion of the image picked up a little bit of the dust around 52 Cygni, but not nearly enough to show how much dust is actually present.  My skies are just not dark enough to shoot the dusty stuff at f/5.5.  I am happy with the amount of faint streamers and the presence of the blue emissions, despite not using an Oiii filter for this project.  (My Chroma Oiii filter  is 31 mm and lives in my QSI camera, which pairs up with the Apex-L reducer and lets me shoot narrowband at f/3.6 with the same telescope). 

The new gear selection system on Astrobin is a bit more data entry than I can handle with multiple filters and multiple acquisition sessions, and it does not allow me to specify Mode 1 / Mode 3 for my camera.  I therefore plan to list filters and acquisition details in the Description from here on, with apologies.

Luminance: Baader 36 mm L 240s, 104 minutes total, QHY268M Mode 3, gain 14, offset 10, Bortle 4
Red/Green/Blue: Baader 36 mm LRGB, mostly QHY268M Mode 3, gain 14, offset 10; one night at dark site, Bortle 4 for the rest
H-alpha: Baader 7 nm 36 mm Ha, 600s, 550 min total, QHY268M Mode 1, gain 56, offset 10, Bortle 4

Dates acquired: June 20, June 25, July 2, July 6, July 20, July 21  of 2022.  Total integration: 18 hours 4 minutes, of which 9 hours 10 minutes are H-alpha.

This nebula image is a change of pace after months of imaging galaxies.  It took so long to acquire the data with poor summer weather that I have already moved onto fall galaxy projects with only this one Milky Way image to show for the summer.  I debated breaking it into two images and processing it with 2x drizzle, which can really produce an impressive close-up effect.  However, I spent so much time on processing this complicated data set that I'm going to be processing another galaxy image by the end of the weekend.  It's time to post this one, and maybe do a revision with 2x drizzle over the winter when I have no new data.
