The two main galaxies in this field are NGC 5850 (SB(r)b) and NGC 5846 (compact
E2+). NGC 5850 is notable due to it's pronounced bar and ring that is seen face
on. There are several other galaxies in this field listed in the NGC (NGC 5831,
5838, 5839, 5841/48, 5845). There are numerous galaxies listed in other
catalogs in this image field as well. Many of these galaxies are members of the
NGC 5846 galaxy group. This image does not have all members since the group
boundary extends beyond the image field. These galaxies
and some of the brighter stars are identified in the annotated
image.. Horizontal FOV is
approximately 38 arc minutes. Image center is located approximately - Equatorial 2000: RA: 15h 05m 55s Dec: +01°43'29"
