Coeli Stella 2000 is an astronomy suite that includes a full-featured planetarium, an observing log and list builder, Coeli Time Line (also known as Stella BC), Live Orbits (orrery), a location browser, Sky Quiz, and sophisticated searches embracing planets, comets, asteroids, DSOs, and up to 300,000 stars. Planetarium-effects include extinction, refraction, and precession in point source, photo plate, and spotlight display styles, and the complete Messier catalog of image icons. An integral HTML guide to the solar system, a 1000-term astronomical dictionary, and the second revised and enlarged edition of Aspects of Astronomy are closely coordinated with the sky display and picture windows.

Stella's Drag Mode brings complete plasticity into all your interactions with the planetarium display. Stella provides direct links to extensive DSO and planetary information on the Web, all tightly unified with the Sky display, Reports, and the Coeli Solar Guide. Auto-Search instantly updates readouts and reports on any object your mouse pointer scrolls over. Complete incorporation of Microsoft Agent speech technology utilizes animated characters to guide you painlessly through the pronunciation of arcane star names and lore, and can read aloud from Astrogloss and Aspects of Astronomy.

It features a Live Orbits window that allows you to view the revolution of planets and asteroids/comets in real time and fast-forward, improved accuracy in the display of the sun, moon, and major planets, a Flash and Track mode that lets you lock onto and follow any object, a new Celestial Globe Projection option, real-time orbit filters, and Viewplane Equator and Eliptic modes.
