My Notes: I captured this at the same time as M60 on which I wrote my notes for this, M58, & M89.
Koehler Notes: (April 11th & 13th, 1779) (M59 and M60) “Two very small nebulae, hardly visible in a 3-foot telescope; one above the other.”
Herschel Notes: (1864) “Bright, pretty large, little extended, very suddenly much brighter in the middle. Two stars precede."
Messier Notes: (April 15th, 1779) “A nebula in Virgo, in the neighbourhood of the preceding (M58)… It is of the same light as that above and as faint. M. Messier reported it on the chart of the comet of 1779.”
