Messier 74

Discovered by Pierre Méchain at the end of September 1780.

Messier: M74.

October 18, 1780. 74. 1h 24m 57s (21d 14' 09") +14d 39' 35"
Méchain: (21d 17' 00") +14d 36' 00"
`Nebula without stars, near the star Eta Piscium, seen by M. Méchain at the end of September 1780, & he reports: "This nebula doesn't contain any stars; it is fairly large, very obscure, and extremely difficult to observe; one can recognize it with more certainty in fine, frosty conditions". M. Messier looked for it & found it, as M. Méchain describes it: it has been compared directly with the star Eta Piscium.'

William Herschel

[PT 1800 p. 70, SP2 p. 43]
Sept. 20, 1783, I viewed the nebula between Flamsteed's 99th and 105th Piscium, discovered by Mr. Mechain, in 1870. [M 74 = NGC 628]
"It is not visible in the finder of my 7-feet telescope; but that of my 20-feet shews it."
Oct. 28, 1784, I viewed the same object with the 7-feet telescope.
"It is extemely faint. With a magnifying power of 120, it seems to be a collection of very small stars: I see many of them."

[PT 1818 p. 448, SP2 p. 600]
The 74th of the Connoissance. [M 74 = NGC 628]
"1783, 1784, 7 feet telescope. With 100 and 120 it its a collection of very small stars; I see many of them."
"1799, 1801, 10 feet telescope. Several of the stars are visible; it is a very faint objects."
"1784, 20 feet telescope. Some stars are visible in it; the edges are not resolvable."
"1805, 1810, large 10 feet telescope. With 108 it consists of extremely small stars, of an irregular figure; a very faint object of nearly 12 minutes diameter."
"1799, December 28, 40 feet telescope. Very bright in the middle, but the brightness confined to a very small part, and is not round; about the bright middle is a very faint nebulosity to a considerable extent. The bright part seems to be of resolvable kind, but my mirror has been injured by condensed vapours."
By the observations of the 7 feet telescope, the profundity of the nearest part of this cluster must be of the 243d order, but most probably a susscession of more distant stars was seen in the larger telescopes.
