The Stars in Six Maps, on the the Gnomonic Projection, revised by the Rev. WR Dawes. Six maps of the stars, published in , is a thin volume with a total of 10 pages: 4 pages of notes followed by 6 plates. It was published by the Society for the Diffusion of Useful Knowledge which was an early 19th century British society who liaised between authors and publishers to produce affordable books on a variety of subjects for a mainly lower and middle class audience, particularly those who . Gnomonic Charts are used in passage planning to plot great circle routes as a straight line. They are useful for devising composite rhumb line courses. A gnomonic map projection displays all great circles as straight lines, resulting in any line segment on a gnomonic map showing the shortest route between the segment's two endpoints.

This azimuthal projection uses the center of the earth as its perspective point. All great circles are straight lines, regardless of the aspect. This is a useful projection for navigation because great circles highlight routes with the shortest distance. Projection method. This is a planar perspective projection viewed from the center of the globe.   John Lubbock: "The Stars in Six Maps on the Gnomonic Projection", London, Edward Stanford, circa , 6 maps as called for, all with hand colour, folio, disbound, printed title page, printed explanation and six leaves of maps. The maps use the Gnomonic Projection and include stars up to the sixth magnitude, of those that can be seen with the naked eye. Originally published by Baldwin and Cradock in .
