NGC 6287

This globular cluster was discovered by William Herschel on 21 May 1784 and cataloged as II 195. He noted the following: «Pretty bright, considerably large, irregularly round, little brighter in the middle.» [463] John Herschel listed it as h 3666 and made the single observation from the Cape of Good Hope on 24 May 1835. He wrote: «Globular cluster; irregular round; gradually pretty much compressed in the middle; 3' diam; barely resolved into stars 16...18m.» [11]

Barnard 47 and 51

In 1919 Edward. E. Barnard found on photographs he made several irregular dark clouds near cluster NGC 6287 and listed them as B 47 and B 51 in his work «On the Dark Markings of the Sky». [239, 609] In 1962 Beverly T. Lynds published her «Catalogue of Dark Nebulae», a compilation of 1802 nebulae that she found on photo plates of the «National Geographic Palomar Observatory Sky Atlas».
