NGC 5297 is a magnitude 12 spiral galaxy in Canis Venatici. Its arms are perturbed by its interaction with smaller lenticular companion galaxy NGC 5296. A faint tidal stream is seen connecting the two galaxies.

This one it turns out has an interesting background. In addition to the interacting galaxies, the companion galaxy has a second nucleus, a compact disturbed galaxy interacting with NGC 5296, barely recognizable in this image as a bluish offset to the core. From this "pair" is a "luminous extension" that leads to a blue quasar shown by the arrow. The curious observation is that that the latter two objects have completely different redshifts, both from eachother and from NGC 5296 and NGC 5297 (which have similar redshifts), despite the assumption that they are all interacting objects.
