Observing Notes

Andrew Cooper
4 Jan 2015 Waikoloa, HI (map)
28cm f/10 SCT, NexStar 11" Gypsy @ 80x

Big, beautiful, rich, a distinct cluster of hundreds of members in a 20' area, quite distinct, fully resolved, a notable orange star at the center (HD 39183 magV 9.16)

12x36 Canon Image Stabilized Binoculars

Good sized, bright, easily found, not resolved, a round patch of fuzz, M36 one field west

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

Large! Rich! beautiful cluster of hundreds of well matched stars, a large central group with several clumps to the sides separated by slight rifts

20cm f/10 SCT

Dimmer than M36 or M38, but far more visible members, yes the magnitude shows brighter, but few bright members gives the eye the impression of a dimmer object, I will not attempt to draw this crowd tonight

Charles Messier
2 Jan 1764

Cluster of small stars, little remote from the preceding [M36], above the parallel of chi Aurigae; the stars are smaller, more close together and enclosing some nebulosity; with an ordinary telescope of 3.5 feet, one has pain to see the stars: this cluster is reported on the Chart of the second Comet of 1771, Mem. Acad. 1777."

Sm. calls this 'a magnificent object;' the whole field being strewed, as it were, with sparkling gold dust; the group is resolvable into about 500 stars, from 10 to 14 mg., besides the outliers. Even in smaller instruments extremely beautiful, one of the finest in its class. Gaze at it well and long. K. notices a brighter star near centre, Burton: ruby: 10, Es.: 9.0: pale red. All the stars in the mass must be nearly at the same distance from us, and consequently their real sizes must be different. The aspect of the Nubucula Major in the S. Hemisphere convinced h. of this: it is ocular proof of the incontrovertible, though long discredited fact, that the apparent brightness of stars has very little connection with their distance from the earth. E. of Rosse, wonderful loops and curved lines of stars, first remarked by D'A.
