New! FocusLock Auto-Focus Software for the ONAG

FocusLockFast, Continuous Telescope Focus Control

Developed in partnership with Innovations Foresight, Optec's new FocusLock software integrates patent pending SharpLock Technology to provide an easy-to-use focusing application that functions whenever guiding is active.  When using the ONAG On-Axis Guider a cold-mirror passes infrared light to the guide camera while reflectiing visible wavelengths on to the imaging camera.  The cold-mirror introduces a slight astigmatism to the guide image allowing FocusLock to quickly determine on which side of focus the camera is currently positioned.  Using the proprietary SharpLock technology, FocusLock can be used to quickly drive the focuser to the optimal focus position and maintain focus for weeks or months at a time.

Full details and Download links available on the FocusLock webpage.

Updated TCF-S driver - Now with ASCOM Local Server

TCF-S FocuserASCOM StandardsOptec has just released a new version of the TCF-S driver software.  Fully compatible with older TCF focusers, version 6 now includes an ASCOM Local Server with the Optec TCF-S Commander acting as a client.  This major change now allows the Optec program to be open and connected simultaneously with other ASCOM clients including Maxim D/L, Sequence Generator Pro, and TheSky X. 

The improvements to the Temperature Compensation routines alone are worth the update.  Now, with the improved Temp Comp Learn Wizard you will have both slope (temperature coefficient, or TC) and the intercept.  This allows the focuser to immediately move to the current best focus position upon startup.  Many users are finding no need to re-focus their telescope for months at a time.

Additional details are available at the TCF-S Focuser Downloads page.
