When dew forms on the optics of your telescope and viewfinder, it makes it virtually useless for observing or astrophotography. Dew shields and other devices can slow down or completely prevent this from happening.
The Telrad Dew Shield attaches to the Telrad Reflex Sight with some simple assembly and effectively slows the progress of dew building up on the reflex glass and the reticle image forming lens. When no dew is present, the Dew Shield can be flipped out of the way.
