Observing Notes

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

Bright and distinct despite being in a heavy galactic starfield, small, not resolved

28cm f/10 SCT Gypsy

A bright well defined open cluster, rich, quite clumpy in appearance with a few notable voids, well over 10' in diameter and reasonably round, homogeneous with a fairly small magnitude variation

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

Rich! a circular patch with a much brighter 8.2 mag. star on one side, resolved but with a mist of unresolved stars surrounding, visible in 9x63 binoculars, a good binocular object

Andrew Cooper
Nov 14, 1998    Empire Mts., Pima Co., AZ (map)
20cm f/10 SCT

Rich star cluster, roughly circular and well resolved

Charles Messier
Jan 7, 1774    

Cluster of very small stars, mingled with nebulosity, which can be seen only with an achromatic telescope. It was when he observed the Comet which appeared in this year that M. Messier saw this cluster, which was close to comet on the 7th of September 1774; it is below the star d Cassiopeiae: that star was used to determine both the cluster of stars & the comet."
