"Helping Astronomers Measure The Stars Since 1979"

Optec is a design and manufacturing firm specializing in electro-optical products used in astronomy, atmospheric science and microscopy. We are located in the town of Lowell, Michigan near the banks of the Grand River. Our company is small but we utilize state-of-the-art equipment and techniques in the design and manufacture of our products.

TCF-LEO Low-Profile Temperature Compensating Focuser

Optec provided a sneak-peak of our new focuser at NEAF 2017 in New York. Visit our booth this year to see the new low profile focuser in action.    The 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 DirectSync Motors for FocusLynx

Optec engineers have designed several new DirectSync motors for the FocusLynx dual-focuser control hub.  DirectSync motors replace the coarse focus knob and provide a direct geared connection to the rack and pinion.  With our smooth clutch mechanism, manual focus control is preserved.  Engage the motor with a simple twist of the motor housing and auto-focus is available using any ASCOM software client. 

New motors include DirectSync SV35 for the new Stellarvue̓̓̓̓ 3-1/2 inch focuser, DirectSync ES25 for Explore Scientific 2-1/2" HEX focuser, and our DirectSync SW30 to fit Sky-Watcher̓̓s premium 3-inch focuser for the Esprit series apochromats.  Visit the FocusLynx page for full details.

We̓ve made a priority of expanding our DirectSync motor selection to include the DirectSync APO, DirectSync TEC, DirectSync ACF, and DirectSync SV for the Stellarvue.  

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.

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.

UPDATED VERSION 1.0.2 NOW AVAILABLE.
