Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 7226. Holden describes this as a "pB Neb connected with a small cluster of stars which radiate in two streams from f to p side. Diam of neb 5', of cl 15', np in p = 315 deg is a small knot which may be nebulous." His "neb" is actually a small cluster, and the "knot" is composed of only four stars. The two streams of stars, pretty clearly visible on the DSS, are probably random field stars. If they are in fact a cluster, the size is about 10 arcmin by 7 arcmin.

Published comments

Trumpler, R.J. (1928)

Trumpler (Lick Obs Bul, Vol 14, No. 420) gives the diameter as 2.5' and the class as 2 2 p. He notes: "Described in the NGC as a nebula in cluster. Photograph with Crossley Reflector (1h 45m, H D Curtis) shows only a small loose cluster of a few dozen faint stars."

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.5 mag open cluster.
