Dan Crowson
 

Arp 3 (MCG-01-57-016 and others) is a low surface brightness spiral galaxy located approximately 60 million light-years away in Aquarius.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 8x300s – 40 minutes each – binned 2x2

 

360 minutes total exposure – 6 hours

 

Imaged September 16th and 17th, 2017 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

I picked up a couple faint asteroids on the first night of exposures. While these rejected out of the final image, you can see them here - https://www.flickr.com/photos/dcrowson/36893425870/sizes/l.

Nice job Dan. Very interesting galaxy as are all the Arp galaxies. I may have to put this one on my list.
