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 7261. JH's cluster is probably the scattered group of pretty bright stars, stretching nearly north-south across an area 15' by 10', about 20 seconds preceding his position for the bright star on its following edge. There is a smaller core (7' by 5') of generally fainter stars about five arcminutes north-northeast of the center of the larger group. Is this perhaps a background cluster?

Published comments

Trumpler, R.J. (1928)

Trumpler (Lick Obs Bul, Vol 14, No. 420) gives the diameter as 7' and the class as 2 2 p.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 10.0 mag open cluster.

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "9M; 7' diameter; 20-plus faint members; just barely an cluster; not overly impressive; inside the isoceles triangle formed by Delta CEP; Zeta CEP and Epsilon CEP; 40' to ESE is cluster N7281."
