NGC 2311: Open Star Cluster (Monoceros) RA: 06h 57.8m / DEC: -04° 36'.7
Instrument: 10-inch Starfinder

Another Monoceros open cluster is presented in the sketch at left. NGC 2311 is offset just southwest of center. 10.4 magnitude Tycho 4809:2552:1 is centered with a 12th magnitude ember glowing immediately to the southeast. NGC 2311 resides 4'.5 to the southwest. At 129X in the 10-inch, the open cluster presents as a 4' diameter misty patch studded along its southern edge by ten mostly 12th magnitude stars. 9.9 magnitude PPM 703228 is stationed just inside the southwest field boundary, 6' from the cluster. The three bright stars at the eastern field edge are--working west to east--7.5 magnitude HD 51722, 7.9 magnitude HD 51783 and, nearest the field boundary, 8.6 magnitude HD 51844. Each member of this trio is separated by roughly a 3' gap. The rest of field is sprinkled with more than 50 stars.
