DEW HEATERS FOR SECONDARY MIRRORS

Due to heat emission into the sky, the back of a Newtonian secondary mirror can become colder during the night, and so the used surface, resulting in the formation of dew. A dedicated heater can prevent from this problem.

Usual heaters cannot be installed on the back of a secondary mirror glued to a holder having almost the diameter of the secondary. The TS-Optics Secondary Dew Heater Kits are the perfect solution, heating the holder and transferring the heat to the secondary mirror.
