Now, the The Night Sky Map and Planet Charts are included in your Astronomy Almanac purchase!
This package includes the original 14400 x 7200 px PNG file, as well as ready-to-print three PDF files to be stitched as a complete map.
The Night Sky Map shows over eleven thousands stars, Milky Way overlay, constellation brightest stars names, lines and boundaries. Included are also objects from Messier catalog and Caldwell list.
The package also includes seven separate charts for all planets of the Solar System and our dearly missed Pluto. The planets are plotted as apparent geocentric position at midnight Universal Time.
