What causes dew on a telescope? When the surface of your telescope objective or camera lens drops below the ambient temperature of the air outside, moisture begins to condense. On a night with high levels of moisture in the air, dew forms even more aggressively. A telescope that has been “dewed-up” no longer captures clear images of your deep-sky target, and instead captures a washed-out featureless image that resembles a flat frame.To be a little more technical, the heat from the warmer telescope transfers to the colder outside temperature via radiation.
