Historical observations

William Herschel (c.1784)

Synonyms: H III-508

Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vF, cL, iE nearly in the meridian."

John Herschel (1847) Cape Observations

Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, pL, pmE, gbM; with an appearance of resolvability, arising as I imagine from a few small stars accidentally on it, as I hardly think it can be reckoned a cluster in the sense of class VI. Re-examined working list. It is III.508. VI.8 does not exist in the space assigned to it in the catalogue." On a second occassion he called it "F, pL, gbM, irregular oval, resolvable, 2.5' by 2'. If this be not VI.8, there is no other near the place. (NB it does not agree with the description of that cluster in my Father's catalogue, which states it to be 8' or 9' in diameter; rich, very compressed. The star 26 x Virginis, by which it splace is there determined, is a mistake for 577 of Mayer's catalogue."
