NGC 3861


Dan Crowson
 

NGC 3861 (NGC 3861A, UGC 3724, PGC 36604 and more) is the spiral interacting with MCG+03-30-094 (NGC 3861B, PGC 36610 and others) near the bottom left of the image. These appear to be located approximately 302 million light-years away in Leo. These along with most of the other galaxies in this field are part of the Abell Galaxy Cluster 1367.  I did notice that some of the galaxies appear to have vastly different distances (for example, UGC 6697 – the long, irregular galaxy on the right appears to be at 438 million light-years away) so these might be close based on the way we view them.

 

Luminance – 24x600s – 240 minutes – binned 1x1

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

 

360 minutes total exposure – 6 hours

 

Imaged April 22nd, 23rd and 24th and December 20th, 21st and 23rd, 2020 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.

Nice framing, Dan.  So many galaxies!

Dan,

 

What a great galaxy field. Lots of different kinds of galaxies. Thanks for sharing.

Great shot with so much going on, diverse sizes and shapes.
