Manhattan Andromeda Galaxy Reprocess

In 2018 I was able to image M31, the Andromeda Galaxy from the High Line during NY's Amateur Astronomers Association outreach sessions from this great urban park. From 12th Street near 10th Avenue we're 1.5 miles from Times Square and clearly in a Bortle 9/ White Zone -- there's a lot of light pollution. Here I have used updated processing tools including a couple of AI utilities to clean up the image.

 

The Andromeda Galaxy is 2.5 million light years from our Milky Way and contains about one trillion stars.

 

Tech Stuff: Borg 55FL/ZWO ASI1600MC/IDAS LPS-V4 filter/iOptron CubePro 8200mount/SharpCap/PixInsight/NoiseXterminator/BlurXterminator/ACDSeeGemstone12.
