Corwin's Notes

===== NGC 7089 = Messier 2. 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.

Steve's Notes

===== NGC 7089 48" (10/26/11): hundreds of relatively bright stars resolved in this large, beautifully symmetric globular. The intensely bright core is overlaid with a mat of resolved stars. 18" (7/17/07): overfills the 8' field at 393x with resolved stars from edge to edge. M2 contains a very bright 3' core that increases to a very intense 1' nucleus. The halo is very symmetric and thins out fairly evenly. A few hundred stars were resolved in the cluster with the central region extremely densely packed. 17.5" (8/2/86): over 100 stars resolved over the entire disc at 286x. Superb view at this magnification. 13" (7/16/82): high resolution at edges, partially resolved core, symmetrical halo. 8" (10/4/80): intense core, faint halo. Faint stars are resolved in the outer halo.
