NGC 3718 (Arp 214) and NGC 3729 in Ursa Major

NGC 3718 (left) and NGC 3729 (right) are two related galax­ies in the con­stel­la­tion of Ursa Major at a dis­tance of 42 mil­lion light years. Grav­it­a­tion­al inter­ac­tion caused the disk of NGC 3718 to be strongly warped, which res­ults in the S‑shaped appear­ance. The galaxy-group above NGC 3718 is Hick­son 56 at a dis­tance of roughly 425 mil­lion light years.

This is the first-light image of my par­ti­cip­a­tion at Black­bird Obser­vat­ory, Sierra Remote (Cali­for­nia), taken by our half-meter RCOS telescope.
