C88

C88 is an informational tool for amateur astronomers. It provides detailed informations about the celestial sphere objects, visible with naked eyes and for the use of an eyepiece of a modest amateur telescope to observe deep sky objects. Complex informations about the planets, sun and moon completes the functionallity of the program. C88 bases on the extensive data of the Bright Star Catalogue (9110 entries) and of the Saguaro Astronomy Club Deep

Alcyone Ephemeris

Alcyone Ephemeris is an accurate and fast astronomial ephemeris calculator covering the period 3000 BC to AD 3500. It calculates heliocentric, geocentric, and topocentric positions of the Sun (Earth), Moon, and planets in ecliptical, equatorial, and horizontal coordinates, with optional corrections for parallax and refraction; rectangular coordinates, velocity, acceleration, apparent diameter, magnitude, phase, lunar libration and more.

Planet's Orbits

Planet's Orbits (for Windows 98/ME/2000/XP) is an accurate digital orrery with a wealth of functionality. The program uses the DE404 ephemeris (accurate for dates between 2000 B.C. and 6000 AD) for the calculation of planetary (except Pluto) and lunar positions. The calculation of the positions of the satellites of Jupiter, Saturn, and Uranus is done by the various analytic theories given in the Explanatory Supplement to the Astronomial Almanac.
