FocusLynx Commander Software and ASCOM Driver

Version 2 represents a major update to the FocusLynx ASCOM driver and FocusLynx Commander software.  After updating, long travel focusers including the FTF3545 can be used without re-syncing the position, step size and MaxStep (maximum travel) are user settable, and the step-micron-mm toggle display allows direct synchronization to the focuser drawtube engraved scale.

Special Note for Windows XP Users

While Windows XP is no longer supported, we do have a batch file available for proper registration of the .msi files.  ASCOM is required, but you may wish to contact Optec support for a customized batch file if you are running into problems with your XP machine.  The most recent version of the XP Setup files are available here.
