Updated TCF-S driver - Now with ASCOM Local Server
Optec 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.
Does Temperature Compensation Really Work?
"Diffraction Does Not Lie" -a famous scientist with funny hair.
Watch a Bahtinov Mask demonstration showing Temperature Compensation in Action. What else to do on a night with really bad skies? How about a test? Using only the built-in temperature compensation of the TCF-S focuser, this video demonstrates that temperature compensation can be very effective at keeping a telescope in focus throughout even minor temperature changes.
