We are pleased to announce our new range of heater bands. Very well made bands with an integreated controller for temperature adjustment. These will connect directly into a 12v power supply with a 2.1mm plug, which is standard on most Skywatcher and Celestron power tanks.

Astrozap Dew Heater Straps are the finest selection for the active dew fighting system. Made in the USA with advanced materials, Astrozap Dew Heater Straps apply heat evenly across the length of the strap. Astrozap stocks Dew Heater Straps for all popular sizes to fit eyepieces, finderscopes and telescope objectives. Astrozap also offers specialty heaters for binoculars, Telrad and Rigel finders.

A Lens Shade/Dew Cap is a tube, of approximately the same diameter as your telescope tube, designed to fit on the front end of the telescope to reduce the amount of dew that builds up on the corrector plate. It also serves as a Len Shade by preventing stray light from falling on the corrector plate, which greatly improves contrast.

We are proud to announce our new range of heater bands with integrated controller and USB connection. These can be connected directly into any USB output for an effective dew solution.
