Flexible dew cap with integrated dew cap heating for ETX105 / C-4

Unheated dew shields can only delay the condensation of moisture on the optics, but cannot prevent it in the long run. In most cases, condensation 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 cut-outs. This refers to a notch for mounting rails, which on some tubes extend far forward, and another for the cable routing of a camera (Hyperstar). You can see whether this model has cut-outs directly from the product title.
