Dew protection especially for Schmidt Cassegrain telescopes from Celestron
The dew protection heater ring is very effective, because it sits directly on the Schmidt corrector plate. This prevents fogging caused by dew.
You can permanently attach the heater ring, which means that there is no need to set up and dismantle it each evening.
