Arp 171 consists of NGC 5718 (UGC 9459 and others) at the center interacting with IC 1042 (UGC 9457 and others) above and to the right. Located approximately 390 million light-years away in Virgo, these are in Arp’s ‘Galaxies with diffuse counter-tails’ class. I’m not sure if he was talking about the faint plumes to the bottom left or something else.
Imaged May 25th and June 5th, 6th, 19th, 20th and 22nd, 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.
Once again, you have pulled in some super distant targets. Great work!
Any idea what the Bortle class is where you image? Back in June, I was traveling cross country and stopped to admire the NM night sky. Absolutely beautiful!
Thanks for sharing your fine work!

Nice shot Dan. To my eye, this pair has diffuse arms that for NGC 5718 seem to weight to the bottom and for IC 1042 seem to be on top. This gives the impression the arms swirl in opposite directions.

Astute observation. Now that you mention it, yes, I agree.
