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.
