M1:

Crab Nebula, Remnant of the SN of AD 1054. M1 is classified as Diffuse Nebula in SC 2000.0. It is noted that it is "Often incorrectly called a planetary nebula."

M8:

Lagoon Nebula

M11:

"Described by W.H. Smyth in 1844 as resembling a 'flight of wild ducks.'"

M13:

Hercules Cluster

M17:

Omega Nebula

M20:

Trifid Nebula

M24:

SC 2000.0 states that Messier describes "the brightening of the Milky Way here" and did not mention small faint open cluster NGC 6603.

M27:

Dumbbell Nebula

M31:

Andromeda Galaxy

M40:

Wnnecke 4, a wide double star; mag 9.0 and 9.6, separation 50".

M42:

"Great Nebula in Orion"

M44:

Praesepe, Beehive Cluster

M45:

Pleiades, Seven Sisters

M47:

Once a missing object; Messier's position erroneous.

M48:

Another missing object. Source of identification given as Owen Gingerich, Sky & Telescope, Vol. 20, Oct. 1960, p. 196.

M51:

Whirlpool Galaxy

M57:

Ring Nebula

M64:

Black-eye Galaxy

M73:

4 stars which the Sky Catalog says are an asterism. Data not in this table but from Open Cluster list.

M76:

Little Dumbbell Nebula

M91:

Another once missing object; source of identification is given: William C. Williams, Sky & Telescope, Vol. 38, Dec. 1969, p. 376.

M97:

Owl Nebula

M102:

SC 2000.0 adopts the view that M102 is a duplication of M101, and claims the identification with NGC 5866 as incorrect. The data here are from their galaxy table.

M104:

Sombrero Galaxy
