Notes: NGC 91 – hard to make out anything. Must be low unit surface brightness. Its core is quite small and I see indications of a large, round, faint halo bigger than NGC 93. NGC 93 – easy to see, slightly oval halo with the major axis aligned nearly E-W, and a weak core. The most prominent galaxy in this field is NGC 80 (13.1m), bottom left in the drawing. NGC 83 (13.6m) was also seen NE of NGC 80. These are not part of the Arp object. |
