Hardcover. Zustand: Good. 1st Edition. The Radcliffe Catalogue of 6317 Stars (Oxford, 1860) is a landmark nineteenth-century astronomical reference, recording the precise positions of circumpolar stars as observed at the Radcliffe Observatory in Oxford. Compiled under the supervision of Manuel John Johnson (1805-1859), Radcliffe Observer from 1839 until his death, the catalogue reflects years of meticulous observation and reduction to the epoch 1845.0. It was issued posthumously with an introduction by his successor, the Rev. Robert Main, and became a key tool for positional astronomy in the mid-Victorian era. The work exemplifies the transition towards increasingly systematic and accurate stellar cataloguing, preceding the great national and international catalogues of the later nineteenth century.
