A star atlas by Winslow Upton, professor of astronomy at Brown, published by Ginn in Boston in 1896 for students and amateur observers with small telescopes. The plates are engraved sky charts on tinted grounds: dotted constellation boundaries, graded dot sizes for magnitude, stippled nebulae and Milky Way, curved ecliptic and equator lines, and spaced capital lettering.
