PGC 198197

Telescope: Hubble Space Telescope, 2.4m Reflector, 57.6m FL
Camera: Advanced Camera for Surveys, Spectral range 350–1100 nm, about 3' x 3' field of view, two adjacent 2048 x 4096 pixels
Image Center (J2000): RA 00h 48m, DEC -25° 07'

Non-interacting, superimposed galaxies in the field of NGC 253. Halo extending from the smaller galaxy’s disk silhouetted by more distant larger galaxy. (2MASX J00482185-2507365), both around 16th mag. The superimposed pair was discovered accidentally in 2006 during an observation of NGC 253. A few papers have been written on this obscure pair since they offer a unique opportunity to study a galaxy beyond its visible edge.
