Description

I'm really happy with how my system has been performing recently. This is a reasonably deep image of Messier 101, known visually for its low surface brightness. There are many background galaxies captured in the image, most missed by the PixInsight Annotation.

This galaxy is thought to be around 28 Million light-years distant and some 200,000 light-years in diameter (SkyTools 4). Other estimates place it at as little as 21 Million light-years.
