From the NGC / IC Project: Contemporary Visual Observation(s) for NGC 7089 NGC 7089 = M2 21 33 27.2 -00 49 23 V = 6.6; Size 16 17.5" (8/2/86): over 100 stars resolved over the entire disc at 286x. Superb view at this magnification. 13": high resolution at edges, partially resolved core, symmetrical halo. 7/16/82 and 11/5/83 8" (10/4/80): intense core, faint halo. Faint stars are resolved in the outer halo. - by Steve GottliebHistorical Research Notes / Correction for NGC 7089 NGC 7089. Shawl and White's position, though correctly copied from their 1986 list, is apparently 2 seconds of time too large. The cluster's image on both POSS1 and POSS2, though burned out in the center, is elongated and symmetric about a position 33 arcsec west of the Shawl/White position. I suspect a typo in their table. Also see NGC 7088. - Dr. Harold G. Corwin, Jr. |
