Thanks for looking. By redshift, approximately 270 million light-years away.

Arp 130 consists of MCG+03-01-016 (PGC 178, VV 263b and others) the spiral that looks like it is interacting with IC 5378 (PGC 177, UGC 1, VV 263/a), the elliptical below it. Redshift data suggests that these galaxies are at least 20 million light-years away from each other so they just look close from our vantage point. Arp has this one in his “E and E-like galaxies – close to and perturbing spirals.” These are located in Pegasus approximately three degrees from Algenib.


The other odd irregular galaxy on the right side is IC 5377 (PGC 156, UGC 12918 and others).


Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 10x300s – 50 minutes each – binned 2x2


390 minutes total exposure – 6 hours 30 minutes


Imaged August 26th and 31st and September 1st, 2019 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.
