Description

My first Astrophotography "Galaxy Season." Continued experiments with the FLT132/2600MC/Powermate2x combo. I'm surprised by how different each galaxy is and how a processing technique for one doesn't necessarily work for another. This was only 40x300". I'm also trying to reduce use of Topaz De Noise and Unsharp Mask in PS to reduce the processing artifacts.

I've also been trying to get away from the split starless processing because of the artifacts left on the stars by StarNet.
