NGC 1618 (PGC 15611 and others) is the spiral at the top right located approximately 120 million light-years away in Eridanus.

NGC 1662 (PGC 15635 and others) is the spiral at the top center. This one is located approximately 216 million light-years away.

NGC 1625 (PGC 15654 and others) is the spiral on the left. This one is located approximately 185 million light-years away.

All of these are somewhat washed out by the glow of the bright (magnitude 3.9 V) variable star nu. Eri (48 Eri, HIP 21444 and others).

Beautiful capture Dan. A lot of great objects in Eridanus, but many are often overlooked. I am certain that this trio doesn’t get imaged much, thanks for sharing!

Hi Dan. A superb image from the remote site in Dark Sky New Mexico at Rancho Hidalgo. A very nice trio of NGC and other objects in Eridanus with excellent contrast and spiral arm details on the flickr site. Thanks for sharing this excellent capture with us on here Dan and and I saw your full page image of NGC 2516 in the December (2022) Sky & Telescope magazine on page 79. :Clap:
