ORION 3517 Dew Zapper Pro 4-Channel Control Module Instruction Manual
Learn how to efficiently prevent dew from forming on your telescope and its accessories with the Orion 3517 Dew Zapper Pro 4-Channel Control Module. This guide explains how the heating band system keeps your telescope's glass just above the dew point, keeping the dew away for as long as the heat is applied. Different sized bands are available to fit your finder scope and eyepieces. Keep the exposed optical surfaces of your telescope clear and use it regardless of damp conditions on clear nights.
