Globular Cluster NGC 6934
History
This globular cluster was discovered by William Herschel on 24 September 1785 using his 18.7 inch reflecting telescope. He cataloged it as I 103 (class I = bright nebulae) and noted: «Very bright, large, gradually much brighter in the middle, easly resolvable, beautiful object.» [464] His son John listed the object in 1833 as a globular cluster with the designation h 2081. [466] Dreyer cataloged it in 1888 as NGC 6934. [313]
