150mm f/17.6 refractor by Tully 1827
A tolerably compressed cluster at the back of the Greater Dog's head, principally composed of stars from the 8th to the llth magnitudes, of which the four principal form the letter Y; there are also some glimpse stars, but to no great extent. Yet to ♅.'s powerful "ken," it appeared to be 20' in diameter, when he observed it in February, 1785. It may be fished up by first finding μ, the object above registered; when it will appear in the nf quadrant, well within a degree's distance.― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844
