Description

Comet C/2021 A1 (Leonard), photographed with a 60mm refractor. 

I registered 2 hours of 3 minute subs to get this image of the comet's motion against the star field. Still very faint at about magnitude 13.

Overall process:​​​​​​
1. Subs: 180s x 40 
2. Stack in AstroPixel Processor with comet registration
3. Auto-tone, Auto-constrat in photoshop, light touch in brightness. 
4. Very light denoising in Topaz (severe profile, 3,3,5,5) 
5. Auto-tone, auto-contrast once more in Photoshop
6. Light touchup to get rid of bad pixels missed by APP.
