CCD Image of the rather unusual Galaxy NGC 5701 in the Constellation Virgo. The inner parts seem to be a barred Lenticular, while the galaxy is surrounded by a faint ring, with H II regions, similar to the arms of a spiral galaxy. There are two small anonymous galaxies in the image, one is superimposed on NGC 5701.
This is a 12 Minute exposure using an SBIG ST-6 CCD camera thru Kopernik's 20 inch telescope (working at F/4.9). North at top; the field of view is about 9x12.5 arc minutes.

Small, very bright diffuse nucleus, bright inner lens 0.55x0.55 arc minutes, bright bar 1.3x0.3 arc minutes. Small companion visible between lens and outer ring at 0.9 arc minutes, Southwest (superimposed), .35x.30; companion at 4.1 arc minutes West, approximately 16th magnitude, .5x.12 arc minutes in size.
This galaxy is a nearly face-on SB0/a galaxy with a faint nuclear source and a large, sparse ring of H II regions in the outer disk of the galaxy, well beyond the bar. .....the outer ring region is also faintly visible.......on the POSS plates.
