Illustration from the manuscript version of the paper ‘Researches in stellar photography. 1. In its relation to the photometry of the stars. 2. Its applicability to astronomical measurement of great precision’, by Charles Pritchard, Proceedings of the Royal Society, vol.41 (1886), pp.195-212. This item was engraved as figure 1 in the printed paper.
Inscribed above with instructions to the engraver: ‘The smaller spaces are required (as usual in Proceedings plates) C.P.’ Other annotations include ‘Black ground’ [indicating that the colour should be reversed to white on black].
Charles Pritchard (1808-1893) British astronomer was elected a Fellow of the Royal Society in 1840.
