Nearby Neighbor

This is the Triangulum Galaxy, also referred to as M33. At a distance of over 2.5 million light-years away, it is a bit further out than Andromeda Galaxy, but it is still one of our closest galactic neighbors. There are around 40-billion stars in this spiral galaxy.

 

I shot this image a few nights ago using about 5 hours of RGB data. I was individually shooting 3-minute exposures in each color, then combining those images to get what you see, here.

Scope: Skywatcher 150 PDS

Camera: ZWO ASI 1600MM with ZWO EFW and filters

Exposures: 30x180s for R,G,B each

Processing: DeepSkyStacker, PixInsight, and Lightroom
