90mm F/12 APO Violet Haze
Nice binocular object, just visible to the unaided eye, not a very interesting telescopic object, sparse, large, coarse, a few dozen stars in a bright clump, a distinct group at the center.

46cm f/4.5 Deep Violet
Big, coarse, sparse, fills the low power field, less than 100 members arranged in small clumps or short sweeps of stars.

Just perceptible to the naked eye; very grand low power field, one of the finest objects in its class. It contains OΣ 44, which see.― Celestial Objects for Common Telescopes, T. W. Webb, 1917

150mm f/17.6 refractor by Tully 1827
A double star in a cluster, between the right foot of Andromeda and the head of Medusa; where a line carried from Polaris between ε Cassiopese and α Persei to within about 2° of the parallel of Algol, will meet it. A and B, 8th magnitudes, and both white. It is in a scattered but elegant group of stars from the 8th to the 13th degree of brightness, on a dark ground, and several of them form into coarse pairs. This was first seen and registered by Messier, in 1764, as a "mass of small stars;" and in 1783 was resolved by Sir W. Herschel with a seven-foot reflector: with the twenty-foot he made it "a coarse cluster of large stars of different sizes." By the method he had applied to fathom the galaxy, he concluded the profundity of this object not to exceed the 144th order.― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844

Fine cluster; about 20 stars of 9m, 10 to 11 m and as many less. Fills field, coarsely scattered. The place given is that of the Double Star h 1123

On September 2,1774, I undertook a closer determination of the position of the star cluster which shows up to the naked eye between Algol in the Medusa's head and Alamak at the foot of Andromeda, and found its separation from Algol as 5°18', from Alamak as 7°6', and from Pi in the Medusa's Head as 4°27', and from p there as 4°51'.
Charles Messier
Aug 25, 1764
Cluster of small stars, between the head of Medusa (Algol) & the left foot of Andromeda, a little below the parallel of Gamma [Andromedae]: with an ordinary telescope of 3 foot one can distinguish the stars. Its position has been determined from Beta, the head of Medusa.― Connaissance des Temps, 1781
