Astrographic Catalogue 1900.0 Greenwich Section Dec. +640 To 900 presents a meticulous record of astronomical observations conducted at the Royal Greenwich Observatory. This volume focuses on the measurement of rectangular coordinates and diameters of star images within the declination range of +64° to +72°. Compiled under the direction of William Henry Mahoney Christie, the catalogue offers invaluable data for astronomers and researchers engaged in celestial cartography, astrometry, and stellar studies. The detailed measurements provide a historical snapshot of the heavens as observed at the turn of the century, making it an essential resource for understanding changes in stellar positions and brightness over time.
