Description

This face-on spiral galaxy is the third-largest member of the Local Group, after M31 and our own Milky Way.

The red so-called H-II regions are glowing clouds of ionized hydrogen, often seen near star-forming areas in the spiral arms. Some of the larger H-II regions in M33 have their own NGC/IC designations.

This is a revisit of a target originally imaged in 2018. This imaging run went deeper by increasing total exposure times and using techniques in PixInsight to bring out the spiral arms and the dark structures.Exposure times were 12 hours each through LRGB filters and 18 hours H-α.North is to the upper left in this image.
