There's an autostar driver on the ASCOM site : http://www.ascom-standards.org/Downl...opeDrivers.htm Maybe that will work.
Meade LX200 Classic and Autostar I (combined telescope/focuser, 5.0.1)
Installs a driver for the original
Meade LX200 ("classic") telescope mounts (including the 16"), as well as Meade telescopes that use the Autostar I (#495 and #497) controllers, such as the ETX and DS series. This driver provides both telescope and focuser interfaces each of which may be used by separate programs. Do not use this with the LX200GPS, LX200R or the RCX400.
