Alcyone Ephemeris Description:

Alcyone Ephemeris is Shareware program for Windows developed by alcyone software

Alcyone Ephemeris is an meticulous and fast astronomical ephemeris calculator covering the span 3000 BC to AD 3000. It calculates heliocentric, geocentric, and topocentric positions of the Sun (Earth), Moon, planets and firm stars in ecliptical, equatorial, and horizontal coordinates (including angular differences between two bodies), with optional corrections representing parallax and refraction; rectangular coordinates, velocity, apparent diameter, magnitude, phase, lunar libration, orbital elements, differences representing all of these, and more. In summation Alcyone Ephemeris offers a wealth of functionality: plotting ephemeris statistics, searching representing precise values, scripting to scribble programs representing more complex computations, qualifying as HTML or Excel files to export output to spreadsheets, discussion processors and web pages, and printing. The ephemeris reckoning is based upon Steve Moshier's analytical ephemeris using trigonometric expansions representing the earth and planets and the lunar ephemeris ELP2000-85 of Chapront-Touzé and Chapront representing the moon, both adjusted to Jet Propulsion Laboratory's DE404. There are other adjustments in Alcyone Ephemeris, some optional, to JPL's more recent DE406, the most meticulous long-term ephemeris. Alcyone Ephemeris is fast. With an Athlon XP 2000+ processor, 100 calculations of geocentric longitude, latitude, and distance representing the suntan, moon, and all planets take around 2 seconds. The ephemeris program itself is also compact, around 20 mgb, compared to approximately 200 mgb of statistics files representing DE406. A encompassing documentation includes tabular and graphic comparisons of calculations with HORIZONS epehemris genarator.

Planets Orbits - Planet's Orbits (seeking Windows 98 / ME / 2000 / XP) is an correct digital orrery with a wealth of functionality. The program uses the DE404 ephemeris (correct seeking dates between 2000 B.C. and 6000 AD) seeking the estimation of planetary (excluding Pluto).

C88 - C88 is an informational tool representing amateur astronomers. It provides detailed informations about the celestial sphere objects, perceptible with naked eyes and representing the use of an eyepiece of a modest amateur telescope to observe deep skies objects.
