Arp 190

Dan Crowson

Arp 190 (UGC 2320, PGC 10755, VV 221 and others) is part of Arp’s ‘Galaxies (not classifiable as E or S) – Narrow Filaments’ class. These both appear to be spirals so your guess is as good as mine on this grouping. Most references mention interaction with PGC 200206, the small spiral above it. There is also a hint of interaction with MCG+02-08-014 (PGC 10738), the elliptical below. Redshift data puts Arp 190 approximately 460 million light-years away in Aries.


Luminance – 32x600s – 320 minutes – binned 1x1

RGB – 15x300s – 75 minutes each – binned 2x2


545 minutes total exposure – 9 hours 5 minutes


Imaged October 4th through the 8th, 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.
