Astrozap Telrad Heater: This heater for the Telrad Red Dot Finder is a fine way to stop dew gathering on the optical glass of the finder. It raises the heat of the optics to a level that, due to temperature differences from the ambient temperature, prevents dew from gathering on your glass optics- thus ensuring that your finder is not left with a hazy view that might lead to mistakes and errors due to dew gathering!
Note: Requires the use of a simple D/C adapter (AZ-719) or dual channel controller (AZ-720) to be powered. Image Note: Finder Scope not included, shown for use purposes only.
