NGC 1097 in Fornax. Five things of interest. 1: a super-bright nucleus showing fine structure. 2: an impressive and well developed bar, with very fine dust lanes.. 3; Star formation in the two spirap arms coming from the ends of the bar. 4: A small satellite galaxy interacting with upper spiral. 5: Spectacularly, two super-faint, very lon, almost dead straight rays (composed of stars, not gas) heading toward 7 and 8 o'clock. These are believed to be tidal tails from interaction with yet smaller but destroyed companions, similar perhaps to our "magellanic bridge". Processing the image so that the core detail and these faint bridges were both visible was a challenge. Aspen 16M on PlaneWave 20 inch.
