About this image

The attached image is of UGC 3697, The Integral Sign Galaxy. This is a mag 13.68 galaxy in Camelopardalis. UGC 3697 is an edge-on spiral 'super-thin' galaxy with warped arms located approximately 151 million light-years away. Scientists believe the warping is the result of interaction with the dwarf galaxy UGC 3714, the (mag 12.6) round spiral galaxy below and to the left (east) of UGC 3697. There are many other faint galaxies in this image, including PGC213372, the mag 17.7, face-on galaxy to the right and just below UGC3714.

One of the challenges in capturing and processing this image is the presence of the two, bright orange stars. HD54070, to the left, is an orange star (B-V 1.1) of magnitude 6.3, and HD52762 is a mag 7 star of a slightly deeper orange hue (B-V 1.3). By comparison, the three blue-white stars to the left of UGC 3697 are mag 10 to 11.
