A minute double star announces this cluster, on the robe under the left thigh of Auriga. A 9½ and B 11, both grey. [this is probably Σ 705 made up of HD 281137 mag 10.1 and TYC 2411-525-1 mag 10.7 separation 18.4" very possibly a binary pair based on Gaia DR2 data with comparable parallax and proper motions, parallax also shows this pair to be a foreground object with respect to NGC 1907]
The object is a compressed oval cluster of 10th to 14th-magnitude stars, about 3' in diameter, trending sf and np, with a pair of l0th-magnitude to the north; in a splendid district of the heavens. It was discovered by ♅. in January, 1787; but the neat double star here estimated, is No. 699 of H.'s Third Series of Sweep Observations. It is about 12° down on the line which the eye projects from Capella towards Betelgeuze, and is there intercepted by another line drawn from Bellatrix through β Tauri, and extended 6½° beyond.― A Cycle of Celestial Objects Vol II, The Bedford Catalogue, William Henry Smyth, 1844
