Description
Here’s M31, the Andromeda Galaxy, our nearest major galactic neighbor, sitting about 2.5 million light years away. This mosaic took 3 panels to capture, combining H-alpha, Luminance, and RGB data for a total of 76 hours and 47 minutes of integration.
Let me know what you think, and as always: clear skies!
