99.7% illuminated #moon, captured as a 2-panel mosaic from my backyard on January 7, 2023.

I tried to keep a delicate touch in processing, in particular to avoid oversaturation and overbrightening that tends to wash out details. #astrodon #astrophotography

A question for comet experts.

I've been reprocessing my C/2021-A1 Leonard photos, and I noticed that if I zoom in on parts of the histogram, I see a teardrop shape close the nucleus. Is this showing the edge of the magnetic cavity?

Shown with exaggerated curves (and then with more regular coloring), with a diagram from the ESA here for comparison:

Still fiddling, but this might be my best one yet. #astrophotography #astrodon

As I get ready for a simple online print shop for my #astrophotography, I've been enjoying retouching photos.
