NGC 7253 is an interacting double system with a bridge between the galaxies, plumes streaming off both, and lots of dust. In the blue, the brightest parts of the galaxies are knots in the disrupted arms. The images smooth over quite a bit in the red, but in the near-infrared, the two galaxies appear almost normal -- thin bulges evenly rising to bright nuclei. It is these bright nuclei that I have preserved as the positions for the two objects, with one of the bright knots in the southeastern object as an optical highlight.
Listed as No. 278 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "diffuse material between galaxies, many internal absorption lanes."
The RNGC (Sulentic and Tifft 1973) notes that this is a 14.5 mag galaxy. Their coded description reads EL,BM,DST,KNS,CURVED.
