Photo description / processing
From yesterday, shooting on 18.04 with UV/IR filter and 23.04 with Antlia Triband RGB Ultra filter.
To avoid stacking and processing two separate files, I stacked everything together, I didn't even change the filter in the file names.
Still, what a great thing a refractor is, no problems with the background, everything is nice and even, and in terms of resolution it easily beats a 200 Newton.
Focal length 640, stacked with drizzle 2, and then the excess was cropped.
