This nice collection of large and small galaxies is located in the northern constellation of Camelopardalis. The most prominent galaxy here is UGC 3697, the curved line at left center, whose common name is the Integral Sign Galaxy. Do you see why this name is a mistake? (Answer at the bottom.)
UGC 3697 is S-shaped because of interaction with another galaxy. For a long time it was supposed that UGC 3714 (the elliptical to its lower left), which is at about the same distance as UGC 3697, was the culprit, but the concensus now is that this is not the case, and that the Integral Sign galaxy has been distorted by interaction with a nearby (unseen) dwarf galaxy. A large part of the right side of the frame contains galaxy cluster Abell 565, a swarm of distant galaxies all lying at the same distance of about 1.3 billion light years.

Answer to question above: although UGC 3697 resembles the mathematical integral sign, it is not one because it's mirror-reversed. It should really be called the Backwards Integral Sign Galaxy!
