Flexible dew cap with integrated dew cap heating for 16" SC

Unheated dew shields can only delay the condensation of moisture on the optics, but cannot prevent it in the long run. In most cases, the precipitation occurs in a flash and the night of observation is over. So why not use a dew shield heater?

Astrozap has now combined both - flexible dew shield and heater in one!

The heated flexible dew shield directs the heat directly onto the optics and thus prevents any dew precipitation - guaranteed!

Astrozap offers its dew shields without, with one or with two recesses. This refers to a notch for mounting rails, which on some tubes extend far forward, and another for cable routing for a camera (Hyperstar). You can see whether this model has recesses directly from the product title.
