150mm f/17.6 refractor by Tully 1827
A double star, A 8, pale white; B 12, dusky. In a loose cluster [NGC 657], between the weapon of Perseus and the elbow of Cassiopea, one-third the distance from α of the latter to α of the former constellation: and it may be fished up by carrying a line from κ Cassiopeae through γ to double the distance beyond.
It was discovered by H., and consists of a gathering of small stars, of 10th to 13th magnitude, divided into two distinct groups; one sf of A, and the other nf. It is a neat but difficult double star, whose angle of position and distance from each other, were very carefully estimated. These observations were made during a vivid and strongly coloured Aurora Borealis.― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844
