M33 - SeeStar
Taken on 11/18/2023 from a bortle 3.5 location after the moon had set.
2 hours and 37 minute of subs.
Single stacked FIT file post-processed as follows:

color correction in ASTAP and file exported as a TIFF.
TIFF imported into Affinity Photo and edited there also using the RC-Astro StarXTerminator and Topaz Anti-noise plugins. Then cropped and exported as a jpg.
