NAME
stars - program to draw a map of the night time sky
DESCRIPTION
stars should be fairly self explanatory. This is a program to display a map of the night sky. It is written purely in C and uses GTK+ widgets along with Gdk-Pixbuf. It uses Glade for the interface design. Except for generating a small rotation matrix and some parameters, all math is integer based, allowing very fast display. At 16 bytes of memory per object, many objects can be loaded at once. Most graphics are antialiased. Currently this program contains data for: 329321 stars(yale bright stars and the ACRS catalog) [points] 23011 galaxies(rc3 catalog) [yellow ellipses] about 10000 galaxy clusters(Abell and Zwicky catalogs) [light blue circles] 1151 galactic open clusters(Lund catalog) [grey circles] 160 galactic globular clusters(Monela et al) [blue crossed circles] Constellation boundaries(IAU 1873 standard) [green lines] Constellations [purple lines] Equatorial coordinate grid(15 min of RA by 5 deg of dec) [red grid] Princeton Pulsar Catalog [blue dots] Galactic and Ecliptic coordinate grids Planetary Nebula [green circles with points]
