Observing Notes

Andrew Cooper
30 Sep 2005 Gila, New Mexico (map)
90mm F/12 APO Violet Haze

The pair is beautiful, two rich concentrations of stars in a rich Milky Way star field, visible to the unaided eye, very nice in 9x63 binoculars, absolutely beautiful in the 90mm scope, NGC884 is larger, sparser, a bright clump with a dim haze interwoven, NGC869 is brighter with a couple bright blues dominating, a little color in the stars but nothing I would call 'ruby' or 'garnet' after Smyth, a nice orange in the space between the clusters

25cm f/10 SCT

Large! Bright! Rich! concentrated, visible to the unaided eye, several hundred members in an even cluster, round, rich star field with NGC884 visible in the same field

94mm f/18 Tully Achromat

These two gorgeous clusters, described by Sm. as 'affording together one of the most brilliant telescopic objects in the heavens,' are visible to the naked eye as a protuberant part of the Galaxy, and so H. considers them. They are often called The Sword Hand of Perseus. With 64 these superb masses are visible together, as well as a bright part north. 5-1/2in. showed a red star between them. Smyth mentions a ruby and a garnet in NGC884. 9-1/3in. shows 5 stars in all. T.T. Smith sees 8. Es. sees 9 in the cluster and outliers, all very similar in color, and spectrum (faint III type). The red stars are all associated with NGC884. Adams finds that all the brighter stars in the cluster have nearly the same radial velocity. Follow the curve of stars north, which leads to the glorious region at 2h 6m, N. 58° 55' [Stock 2].
