150mm f/17.6 refractor by Tully 1827
A very extensive and compressed cluster, on the right side of Perseus, in a rich portion of the galaxy; and it has a gathering spot, about 4' in diameter, where the star-dust glows among the minute points of light. This elegant sprinkle was registered, in December, 1786, by ♅., who says, "the large stars are arranged in lines like interwoven letters." It is H.'s No. 290, of the Catalogue of 1833: I derive its mean apparent place by differentiation from α Persei, from which it lies at an angle = 9° with the vertical, at a distance of nearly 8° in space.― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844
