NGC 6293

This globular cluster was discovered by William Herschel on 24 May 1784 and cataloged as VI-12. He noted the following: «Another miniature cluster like thee preceding [M 19], but rather coarser.» [463] John Herschel first observed it at home in Slough during sweep 148 on 16 April 1828 and listed it as h 1977 with the note: «Very bright, round, preddy suddenly brighter in the middle; 90"; resolved; the stars are 19 or 20 m. This then is entitled to the name of a globular cluster.» [466] Later during his observation in 1834-1838 from South Africa he observed the same cluster twice and listed it as h 3667. [11]
