Adastra Plus is a complete astronomy experience that offers real-time sky, comprehensive reports, animation, and live orbital tracking. It 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; track any selected object through the sky in both real-time or fast-forward.
Adastra's 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 navigational ease to the sky display for smooth, head-turning views of the heavens.
