Observing Notes

Andrew Cooper
17 Nov 2009 Hale Pohaku, HI (map)
46cm f/4.5 Newtonian, Deep Violet @ 95x

A large, bright and sparse open cluster with members arranged in clumps over a 15' area

Andrew Cooper
4 Apr 2007 Waimea, HI (map)
76mm f/6 APO

A rich and bright cluster above the head of CMa, very distinct and well detached from the rich winter Milky Way background, fully resolved, about a dozen 8-9th magnitude members dominate a rich faint population, about 15' across

Andrew Cooper
15 Nov 1998 Empire Mts., Pima Co., AZ (map)
20cm f/10 SCT

Interesting cluster with many sweeping arcs of stars, a red star just south of the main body

John Herschel
8 Jan 1831

Superb cluster; fills whole field; irregularly round; stars of 11th to 15th magnitude; not compressed in the middle; straggling stars extend over a circle 30' in diameter.

Charles Messier
5 Jan 1772

Cluster of small stars, more or less brilliant, above the right loins of the Unicorn, above the star Theta of the ear of Canis Major, & near a star of 7th magnitude. It was while observing the Comet of 1772 that M. Messier observed this cluster. He has reported it on the chart of that comet, on which its trace has been drawn. Mem. Acad. 1772."

Rev. T.W. Webb
Hardwick, Herefordshire, England (map)

Brilliant cluster, straggling, h. says, to 30'; containing a red star; between Sirius and Procyon, 1/3 nearer the former, in a superb neighborhood, where the creator has-- 'Sowed with stars the heaven thick as a field.'
