AstroPlanner is a software application for Macintosh and Windowscomputers that facilitates astronomical visual observation planning andlogging as well as control of Meade telescopes that use the LX200,LX200GPS or Autostar controllers, Celestron NexStar scopes,Astro-Physics GTO mounts, the Vixen SkySensor 2000 system , and severalothers. It also incorporates the Best Pair functionality for selectingoptimum telescope alignment stars and tools for facilitating iterativeand drift polar alignment via computer control of the telescope.It is designed to enable the observer to set up a list of astronomicalobjects he/she wishes to observe. These are either entered manually, bylookup in the supplied database of astrometric catalogues (e.g. Messier,NGC, SAO, etc.), or by importing them from suitably formatted textfiles. Solar system objects are also supported (sun, moon, planets,comets and minor planets) and comet/minor planet orbital elements can beimported in the usual formats (from a range or sources including theASTORB and MPCORB databases).
