FocusLynx Multi-Instance Driver

FocusLynxOptec has released a new FocusLynx driver package allowing control of multiple hubs from a single computer.  This public beta release software can be used with a single FocusLynx hub or several hubs at the same time.  Each hub can control up to two focusers through the standard ASCOM chooser.  Intelligent instance control keeps track of which ASCOM client is connected to which focuser.

If you own two or more FocusLynx or FocusBoss II control hubs, download and try our new software today. Download TCF-S ASCOM driver

FocusLynx Hand Control upgrade

Optec has added a Fine Focus Knob to the FocusLynx Hand Control for a much better experience at the telescope. With three speeds and improved response of the IN and OUT buttons, you'll find using the Hand Control much more enjoyable for visual observing. Single handed operation allows you to adjust focus quickly and precisely without moving your eye away from the eyepiece. If you're a visual user with the FocusLynx system,  you owe to yourself to try the new hand control.

Contact Optec Sales to arrange return of your hand control for upgrade at a special upgrade price.    Includes the latest hand control firmware and works best with the current versions of FocusLynx Commander.

TCF-LEO Low-Profile Temperature Compensating Focuser

Optec provided a sneak-peak of our new focuser at NEAF in New York over the weekend.  The new TCF-LEO is the newest in our line of temperature compensating focusers.  This thin low-profile focuser has a minimum thickness of only 1.25" and 0.35-inches of travel or about 9mm. 

We anticipate the TCF-LEO will help many imagers struggling with minimal back-focus on scopes such as the Celestron EdgeHD C1100.  TCF-LEO is designed to fit between the mirror lock-knobs on the C-11HD and will work well with the Innovation Foresight On-Axis Guider as well as the large Perseus 3-inch port. Click here for more information.

New! FocusLock Auto-Focus Software for the ONAG

FocusLockFocusLock  Fast, 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.  SharpLock has received a Sky & Telescope Hot Product award for 2016.    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.
