FocusLock Software

Fast, Continuous Focus for any ASCOM Focuser

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 software, a single system gain constant, Ks can be used to quickly drive the focuser to the optimal focus position and maintain focus.

FocusLock is designed to maintain focus whenever the guide camera is operating.  Guiding can be accomplished through Maxim D/L, TheSky X, and PHD2 Guide or any other guiding program using the Optec ASCOM Server.  Focuser control and filter focus offsets are supported for any ASCOM filter wheel.

Auto Calibration wizard is included with manual calibration overides.  Scripting for external program control and focus verification is now included for observatory automation.
