North is up in this image.  This is an image of the galaxy NGC 660 and a wider field showing background galaxies. NGC 660, SB(s)d pec, is a peculiar galaxy having what appears to be two galactic planes - each with dust lanes. It is about 43 million light years distant.  Some of the smaller nearby galaxies are LEDA 6368, UGC 1200, UGC 1211, and IC 148. There are various Quasars  visible in this image - the greatest lookback time is 11.56 billion light years with a redshift of 3.018 These objects, information, and some of the brighter stars are identified in the annotated image Horizontal FOV is approximately 89 arc minutes. Full size image scale is approximately 1.29 arcsec/pix.. 

Image center is approximately - Equatorial 2000: RA: 01h 43m 03s Dec: +1333'43"
