Arp 338, the last galaxy on Arp’s list, is just classified as miscellaneous. It looks like this one is designated as PGC 154807. Some catalogs give the ‘bar’ a designation of PGC 3094767. I would guess that the bar is another galaxy but I could not find any information to confirm this. These are located at an unknown distance in Sextans.

PGC 1011898 and PGC 1011946 are the more Arp-like pair above and to the right.

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

360 minutes total exposure – 6 hours

Imaged February 10th, 11th and 18th and March 5th, 2021 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.
