Half-Hours With the Stars: A Plain and Easy Guide to the Knowledge of the Constellations, Showing in 12 Maps, the Position of the Principal ... Night Throughout the Year
Excerpt from Half-Hours With the Stars: A Plain and Easy Guide to the Knowledge of the Constellations, Showing in 12 Maps, the Position of the Principal Star-Groups Night After Night Throughout the Year
It is necessary, perhaps, to point out that this work is intended as a companion to a series of star-charts, not as in itself a star-atlas. The possessor Of a good star-atlas will find that this work serves the purpose of a key to the atlas; and, on the other hand, the possessor of the present work will find that an atlas is needed to exhibit the details of constellations.
We do not at present possess any satisfactory atlas sufficiently cheap for general use. I am pre paring, however, a small atlas, reduced from my large one, which will present many advantages over any at present in existence. Although the work will be small and handy - such a book as the Observer can conveniently carry in his pocket - the superficial scale will be half as large again as that of the S. D. U. K. Smaller atlas, each map of which occupies a sheet some 16 inches square. Yet each map Of the series will cover a tenth part of the heavens, the reduction in size being simply obtained by the adeption of a scheme which reduces the distortion to an absolute minimum.

About the author
Richard A. Proctor
487 books2 followersRichard Anthony Proctor (23 March 1837 in Chelsea, London – 12 September 1888) was an English astronomer.
He is best remembered for having produced one of the earliest maps of Mars in 1867 from 27 drawings by the English observer William Rutter Dawes.
His map was later superseded by those of Giovanni Schiaparelli and Eugène Antoniadi and his nomenclature was dropped (for instance, his "Kaiser Sea" became Syrtis Major Planum).
He used old drawings of Mars dating back to 1666 to try to determine the sidereal day of Mars. His final estimate, in 1873, was 24h 37m 22.713s, reasonably close to the modern value of 24h 37m 22.663s. Nevertheless, Frederik Kaiser's value of 24h 37m 22.622s is closer.
A crater on Mars is named after Proctor.
