Description

Came back to an old favourite here and this time had a go at the target including hydrogen star-forming regions which I have tried to keep subtle, as they have a tendency to overpower images. When I began astrophotography I use to add hydrogen to galaxies with Photoshop, but the Pixelmath function in PixInsight has proved to be a much more effective tool.  Thanks to 'Galactic Hunter' for the guide on how to do this.
