Program description

A complete astronomy experience is in store -- with real-time sky, comprehensive reports, arcsecond accuracy, and exciting features such as animation and live orbital tracking. Adastra's powerful search encompasses planets, comets, asteroids, DSOs, and a multitude of stars, making exploration of the sky in real time easy. The natural Drag Mode introduces a new navigational ease to the sky display, for smooth, head-turning views of the heavens. Adastra's point-and-click Sky Quiz will quickly build familiarity with your local celestial geography, leaving "Solar Guide" and "Astrogloss" to supply trusted encyclopedic information in HTML form. Solar Guide takes you on a tour of our Solar System interactively linking to both Sky and Picture windows. Astrogloss A-Z is a dictionary of over 1000 astronomical terms, integrated tightly with Adastra's Search and display. So when you click on an object in the sky, Adastra will bring up that object's definition in the Dictionary. A precision tool for the archaeo-astronomer, Coeli's TimeLine (alias "Stella BC") can graphically demonstrate the dramatic effects of precession down through the millennia, seeking out that remote First Time, when Vega and Deneb were Pole Stars... Adastra offers five celestial projections in which to observe the night sky on your PC, in either resizeable windows or full screen mode. Advance, retard, or animate the simulation's clock by years, months, days, and minutes of sidereal or solar time; track any selected object through the sky in both real-time or fast-forward. A NEO asteroid 'chase' is recommended as an introduction to this absorbing activity. And don't forget to open the Live Orbits window...
