Arp 25 (NGC2276, UGC 3740, VV 1189a and others) is an intermediate spiral galaxy in Arp’s ‘spiral galaxies with one heavy arm’ class.

Arp 114 (NGC 2300, UGC 3798 and others) is the elliptical pulling on Arp 25. It is part of the ‘elliptical galaxies close to and perturbing spiral galaxies’ class.

Both of these are located approximately 120.5 million light-years away in Cepheus.

Luminance – 24x600s – 240 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

360 minutes total exposure – 6 hours

Imaged over five nights in November and December, 2017 and January, 2018 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.

This object is fairly low so seeing was between bad and worse for most of the imaging time. I probably discarded as many exposures as I kept.
