Description

With 14 pages of images in Astrobin, M104 is a movie star. It’s not easy to match the wonderful images of the Sombrero that have already been published.

My goal with this image was to improve my processing skills in small ways. I tried for proper star and galaxy colors, decent interior detail, controlling star bloating, lack of color casts and gradients, and avoiding blown-out stars.

This is an RGB image.
