Description

This rather dim obscure object was in a good position to fill some blank space in my imaging schedule, so I collected over 200 RGB images and PI selected the 62 best for this image.

Workflow:

In PI, photometrtic correction, crop and DBE only from corners. Repeat the photometric correction to try to make sure colors are correct. Add super-L from all 62 registered RGB.

In PS Topaz-AI denoising, set black point and then S-curve stretching. 3D- LUT to brighten/separate colors and then stars fixed.
