North is up in this image. M95 and M96, a pair of galaxies in the constellation of Leo, are the two large galaxies in the image. M95 (also known as NGC 3351, UGC 5850) is an SB(r)b galaxy with noticeable bar and ring; M96 (also known as NGC 3368, UGC 5882) is an SAB(rs)ab galaxy. M95 and M96 are at a distance (redshift independent estimate) of 32 and 35 million light years respectively. All other galaxies in this field are background - at least an order of magnitude further distance. There are a number of Quasars (one a quasar candidate) in this field - most with redshifts greater than 1.0 with light travel times (Lookback) ranging from 8 to almost 10 billion light years. These objects and some of the brighter stars are identified in the annotated image. This iamge replaces an earlier image in the archives here. Horizontal FOV is about 83'. Full size image scale is 1.25 arcsec/pix.
Image center is approximately - Equatorial 2000: RA: 10h 45m 30s Dec: +11° 30' 19"
