Arp 74


Dan Crowson
 

Arp 74 consists of UGC 1626 (PGC 8161 and others), the spiral at the center and Arp 74B (2MASX J02082216+4128061) the small galaxy below it. Arp includes these in his “Small, high surface brightness companions on arms.” While I could not find any information on distances, it is highly possible that Arp 74B is much more distant than UGC 1626 with no interaction at all. These are located about three degrees from NGC 891 in Andromeda.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 10:8:10x300s – 50:40:50 minutes each – binned 2x2

 

410 minutes total exposure – 6 hours 50 minutes

 

Imaged October 16th and 17th, 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.

The diminutive size does not take away from the unique arms.  A unique composition.  I like it.
