Observing Notes

21 Oct 2006 TIMPA, Avra Valley, AZ (map)
12x36 Canon Image Stabilized Binoculars

Bright and easy to find when scanning the summer Milky Way, good sized, not resolved, a round patch that stands out well against the Milky Way glow

46cm f/4.5 Deep Violet

Rich cluster in a rich Milky Way star field, about 10' in diameter, cluster members surprisingly even in magnitude with one very bright orange star, a number of very obvious rifts divide the cluster into uneven clumps

20cm f/10 SCT

Bright cluster, easily visible in the finder, bright star at the center, hundreds visible, but in the Milky Way, who is to say if any particular star is a member of the cluster

John Herschel
23 Jul 1827

A beautiful irregularly round cluster 10' or 12' in diameter. The stars are all of 11th magnitude except one which is of 9th magnitude, whose place is taken. Examined with high magnifiers [I have often viewed it with magnification 800 and even 1200]; it is broken into 5 or 6 distinct groups with rifts or cracks between them.

Charles Messier
30 May 1764

Cluster of a great number of small stars, near the star K of Antinous [ Scuti], which one can see only in a good instrument; with an ordinary telescope of 3 feet it resembles a comet: This cluster is mingled with a faint glow; in this cluster there is a star of 8th magnitude. Seen by Kirch in 1681. Phil. Trans. No. 347, p. 390 [Halley]. It is reported on the English Great Atlas. "

94mm f/18 Tully Achromat

Noble fan shaped cluster, ""magnifica innumerabilium stellarum coacervatio"" (D'A.) [a magnificent accumulation of innumerable stars?]; at the upper edge of a broad luminous cloud which marks the shield of Sobieski. Sm. compares it to a flight of wild ducks. H., stars 11 mg. divided into 5 or 6 groups, noted independently with 5-1/2ft. An 8 mg. star is a little within its apex; an open 8 mg. pair sf beyond it. H., just visible to naked eye. Sometimes placed in Scutum Sobieskii. Ellison notes ""dark structures"" plainly visible.
