Software
Of all the planetarium software programs out their which is the most
accurate as far as the positions. Like RA Dic, AZ Alt of the planets and stars and rise and set times? I tryed several and none match up with MICA from the naval observatory. Red Shift is way off. |

Sky Charts ( Cartes du Ciel, http://www.stargazing.net/astropc/download.html ) is a very good freeware planetarium program. On this site you will find additionnal high-precision planetary catalogs. I do not know it it does match MICA but i believe that on the screen, the difference will be less thqan a pixel anyway... Benoît Morrissette |

Bill Gray likes to be able to boast that Guide www.projectpluto.com is tops for accuracy - it will do things like accurately show the occultation of 28 Sagittarii that happened some years ago. Most programs agree to within a few seconds AFAIK, but you have to wonder why some of them don't - are they using a poor model, or messing up the calculations based on it? -- "Forty millions of miles it was from us, more than forty millions of miles of void" |
