Corwin's Notes

===== NGC 2250 is placed 1 minute of time too far west in RNGC and in the Alter and Ruprecht star cluster catalogue. JH recorded as the position that of the 8th magnitude star we now call SAO 133414, though that is on the eastern side of the cluster. I now (February 2014) make the approximate center is about five arcminutes west-southwest of that star, based on JH's full description: "Place of a *8.9 m in foll[owing] part of a L p rich loose cl; irreg oblong fig; sts 12 ... 14 m." I've taken the western edge of the cluster to be the star at 06 30 34.0, -05 03 19. If only stars closer to JH's bright star are considered, then the position will move back east a bit.

Steve's Notes

===== NGC 2250 18" (1/26/09): at 175x about two dozen stars mag 12-14 stars are resolved in an 8'x4' irregular group, elongated E-W. The brightest star is mag 8.7 HD 46576 on the NE end. Includes several pairs, although none are impressive. Set over a glowing Milky Way background. Appears to be just a weak field enhancement not a true cluster.
