The download is a zipped file that includes a read-me file with complete instructions on installing the ASCOM Platform and using the plug-in. The ASCOM Platform installs the plug-in which allows users to control the following telescopes from within Starry Night:Orion SkyQuest IntelliScope.Meade LX-200 and Autostar-equipped robotic telescopes (such as the ETX 90/125 and LX200 GPS).Celestron Ultima 2000, Nexstar 5, Nexstar 8, Nexstar 11 GPS and Nexstar 114 GT telescopes (will not work with other Nexstar models).Generic LX-200 Type Scopes. The Generic LX-200 driver uses the absolute minimum of the LX-200 control protocol, and is thus compatible with a wide variety of amateur type telescopes and mounts that use so-called LX200 emulation. The following telescopes and mounts support the generic LX200 protocol (there may be others): Astro-Physics AP series, Astro-Electronic FS-2, Losmandy Gemini, Mel Bartels Controllers.ACL Based Telescopes. This includes many types of research-grade telescopes controlled using Astronomy Command Language. Any telecope controlled by either of these packages is accessible via the ACL-based Telescope driver. This includes most Optical Guidance, DFM, Optomechanics Research, SciTech and Merlin research telescopes and mounts.Vixen SkySensor 2000.Astro-Physics 1200 GTO.AstroOptik research telescopes.Astrometric Instruments SkyGuide TCS.Telescope Simulator (for testing)*Digital Setting Circle computers that recognize the Meade LX200 generic protocol - such as the Argo NavisMacintosh.On the Macintosh, Starry Night Pro controls telescopes with its own telescope plug-in.
