Purchase OCS ASCOM Driver

For my Observatory Control System (OCS)

Thank you for your consideration and support!

PayPal handles the payment processing of these OCS ASCOM drivers which cost $19.99

I’ll then provide you with two OnCue OCS compatible drivers:

  • An ASCOM Dome driver for opening and closing a shutter or roll-off-roof (not for actual Dome movement.)
  • An ASCOM Safety driver for reading the safety status from my OCS firmware.


Notes: These drivers do not include ASCOM Switch, Weather or Dome control.


An updated OnCue OCS unified driver (Beta, for user testing) is also available and will be provided. This driver requires the latest OCS software, version 3.09a or later and supports the following features:

  • USB/Serial or IP connections.
  • Multiple client connections across a single serial interface.
  • An ASCOM Dome driver for opening and closing a shutter or roll-off-roof (not for actual Dome movement.)
  • An ASCOM Safety driver for reading the safety status from my OCS firmware.
  • An ASCOM Observing Conditions driver for using the weather sensor data in client applications.


Please provide your full name and email address in the notes section or an email to hjd1964@gmail.com when ordering and allow up to 24 hours for me to get back to you with the installation files in an email.
