| Notes: | Comments from "Star Clusters", by Brent
Archinal & Steven Hynes; "Archinal: DSS shows obvious N-S stream
of bright stars, with large bright nebula involved on SW side." The
"large bright nebula" is the Northeastern outlying portions of the the
Rosette Nebula. See this
interactive
image of the Rosette Nebula from Davide De Martin. According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of this open cluster is 18 arc minutes. From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 2252NGC 2252 = Cr 102 = OCL-514 = Lund 233 06 34 19.8 +05 19 22 V = 7.7; Size 18 18" (3/13/04): at 115x, this fairly rich field is located just 50' NE of the center of the Rosette Nebula (N2244)! Most distinctive in the field is a very elongated N-S group of roughly 50 stars in a 12'-15' string just 2' wide. The group has a distinctive hook on the north end as it curves sharply towards the SW. A near perfect triangle of mag 9 stars at 30", 34" and 40" separation lies 23' E. - by Steve Gottlieb |
