Description

Arp 1 (NGC2857) in one frame with Arp 285 (below right - an interacting pair of galaxies).

Arp 1 is the beautiful little spiral in the center of the frame. It very much resembles the Pinwheel Galaxy in my opinion. In Arp's Atlas of galaxies it is categorized as low surface brightness galaxy. Its distance is 225Mly and measures 125000ly.

Arp 285 below to the right is an interacting pair of galaxies. Both are spirals. NGC2854 is quite a bit larger (65000ly) compared to NGC2856 (35000ly), which comes at a distance of 119Mly. The former is 125Mly away from earth .

This will receive color treatment, when skies allow!
