Description

Sculptor Galaxy is 11.4 million light years away. A magnificent, bright galaxy surrounded by a plethora of background galaxies, and a few very recognizable foreground stars.

This is my first relatively deep LRGB integration with the new toys. There have been some issues in these captures, both optical, guiding, mechanical... but the resulting image is decent enough.

I captured this image in 3 sessions the 10th, 13th and 18th of October 2020. The first 2 sessions had issues that prevented me from acquiring much data, hence the "short" integration given that I spent 3 nights acquiring data.

I combined all RGB channels together, built a superluminance channel combining luminance with RGB, and then combined it all. I applied considerable noise reduction to clean up the background, and stretch as much as noise will allow me to.

I'm going to need a lot more integration time to properly bring out those background galaxies, so I decided to publish it in this form for the time being.
