150mm f/17.6 refractor by Tully 1827

A neat double star close to the Præsepe on the Crab's body; and the "cloudy Præsepe" group is visible to the inquiring eye, at one-third of the distance between Pollux and Regulus. A 7, golden yellow; B 10, blue. This object is the southern member of a triangle, and is preceded by three pairs of stars, all of which were measured by Sir James South. The former registers of this are:
    S.  Pos. 52° 58'  Dist. 20".69  Ep. 1825.14
Σ. 53° 51 20".52 1831.31
[WDS 55° 20".80 2017 ]
The reductions of A show some slight aberrations from the common laws of precession, which are thus valued:
