Proper Motion - Software

Software

There are a number of software products that allow a person to view the proper motion of stars over differing time scales. Two free ones are:

• Moovastar - Freeware - Windows, Fairly Basic. You can choose a region of the sky, set the limiting magnitude and set a time sequence (time step, number of steps, and step interval). The program will simulate the motion of the stars. There's a clear help function included.
• HippLiner - Freeware - Windows, Moderately sophisticated, with some pretty displays. Still under development, needs some more navigation and configuration features.
