Johann Bode discovered M92 = NGC 6341 on 27 Dec 1777. Charles Messier independently rediscovered M92 on 18 Mar 1781. WH's earliest observation was on 25 Aug 1783 using his 12-inch, calling it "A most beautiful sight. I can count 50 or 60 stars besides numberless that only distinguish themselves by twinkling..." JH has no observations listed in his Slough Catalogue. Christian Peters reported finding it around 1850, while at Capodimonte Observatory in Naples and claimed it did not appear in any of the books.

200/250mm - 8" (7/9/80): very bright, moderately large. Well resolved into many long streamers from the small bright nucleus and some core resolution.

300/350mm - 13.1" (6/29/84): highly resolution over entire disc, dozens of stars resolved in bright core. A bright knot in the core is partially resolved at 416x.
