Kendrick Split Newtonian Secondary Heater
The Kendrick split ring style Newtonian secondary dew heater is designed to fit directly to the glass of the secondary mirror with a thinner central stalk, including Meade Light Bridge, Orion USA Intelliscope Dobs, Orion UK Newtonians and Dobsonians, and most Skywatcher Newtonians.
The dew heater is flexible, so it can easily be placed around the mirror stalk, and then the heater is glued to the back of the mirror using just a few small dabs of glue or silicon sealer.
This heater works will with secondary mirrors of around 75mm (3.00") or larger. The heater warms the mirror slightly above ambient temperature, and clears away dew or condensation. Once the mirror is cleared, you can leave your Kendrick controller on at a low power setting (about 10%) and the mirror will remain free of dew. In extreme conditions you can increase the power as needed. These heaters are very efficient at converting electricity to heat and very little power is required.
