Generate Star Chart

Specify Position, either by selecting a constellation, or location (by R.A. and declination or by planet) and scale. Constellation overrides location and scale.

Constellation: use coordinates Andromeda Antlia Aquila Aquarius Aries Auriga Bootes Caelum Camelopardalis Cancer Capricorn Cassiopeia Centaurus Cepheus Cetus Canis Major Canis Minor Columba Coma Bereneces Corona Borealis Capricornus Corona Australis Crater Corvus Canes Venatici Cygnus Delphinus Equuleus Eridanus Fornax Gemini Grus Hercules Horologium Hydra LAC Leo Lepus Libra Leo Minor Lupus Lynx Lyra Microscopium Monoceros Norma Ophiuchus Orion Pegasus Perseus Phoenix Pisces Piscis Austrinus Puppus Pyxis Scorpio Scutum Sculptor Serpens Cauda Sextans Sagitta Sagittarius Serpens Caput Telescopium Trapezium (Orion) Taurus Triangulum Ursa Major Ursa Minor Vela Virgo Vulpecula

Label Magnitude Range

Center magnitude:
delta:
Label stars with their magnitude, as for variable star or asteroid finder charts. The first argument is the center magnitude, and the second a range: stars within plus or minus range of the center magnitude are labeled.

Grid

Spacing: R.A. Dec
Origin: RA Dec
A grid isdrawn, with arbitrary spacing in R.A. and declination.

Other options

Invert. The main map of the chart is dawn with north and south flipped, to produce an inverted view.
