This object is a distant, rarely imaged, tiny pair of interacting, edge-on galaxies located 400 million light years away in the constellation of Draco at a declination of +60 degrees. The width in our apparent view of the total object is 1.1 arc-minutes, which corresponds to a width of 130,000 light years.

Although Hubble images and subsequent studies show that these two galaxies are interacting significantly, that is not obvious to me in my image. I don't see any star streams and the two disks are fairly undisturbed. One sign of interaction is the slightly warped disks. Another is the reddish tint of both galaxies, suggesting the presence of HII and indicative of star formation. The likely star cluster at the right edge of the object is also a sign of star formation. Perhaps the interaction planes of these galaxies are oriented such that the formation of star streams and significantly warped galaxies is not possible.
