As of August 2022, we no longer host drivers here. Drivers formerly hosted here have been moved to the ASCOM Ghost & Legacy Drivers repository on GitHub.
Software and drivers for the Seletek family of controllers. Separate ASCOM drivers are supplied for up to three simultaneous devices (focuser, rotator,
dome...). The rotator will drive VSI's Zerotator and any DIY, stepper based ones.The button takes you to the Optec, Inc. download page for their drivers. Optec supplies and supports ASCOM drivers for their devices. The RC Optical Systems Telescope Command Center (TCC) software includes an ASCOM standard rotator driver. For more details visit the RC Optical web site, or contact the manufacturer.
