Decent, medium sized globular, stars easily resolved

John Herschel
13 Oct 1825

Very bright; very large; irregularly round; gradually brightening and very suddenly much brighter toward the middle. A magnificent globular cluster; comes up to a perfect blaze in the centre, like a protuberance or nipple; not the condensation of a homogeneous globe; it has straggling streams of stars, as it were, drawing to a centre. It is not round. Has a star of 8th magnitude, 30 sec following in parallel.

Charles Messier
11 Sep 1760

Nebula without a star, between the head of Pegasus and that of Equuleus; it is round, in the center it is brilliant, its position was determined by comparison with Delta Equulei. M. Maraldi, in the Memoirs of the Academy of 1746, reports of this nebula: ""I have found, he says, between the stars Epsilon Pegasi and Beta Equulei, a fairly bright nebulous star, which is composed of many stars; its right ascension is 319d 27' 6"", and its northern declination is 11d 2' 22""."

24cm Reflector

Bright and resolvable (h., 15 mg.), blazing in centre; a glorious object with 9-1/3in. 'With' mirror. Very fine specimen of a completely insulated cluster, discovered by Miraldi, 1745. Buffham, with 9 in. spec. finds a dark path near the middle, with two faint dark 'lanes' or rifts, like those in M13, unnoticed by h. or D'A. 51 variable stars have been discovered in this cluster.
