Astrozap Flexible Dew Shield for D=298 mm - 10" TS/GSO RC / Meade SC

Flexible dew shields from Astrozap protects against dew and stray light.

Glass surfaces directed to the clear sky radiate much heat, cool down and might fog up during the night. They also tend to collect stray light from the side, reducing contrast. The usually blackened rear side of the secondary holder also emits heat and can cause foggging of the secondary mirror.

Flexible dew shields from Astrozap narrow the area of the sky as seen from the front surface, reducing the heat emission and therefore the risk auf dew formation. As there is no chance of light coming from the side anymore, contrast is largely kept even close to light sources.

At the same time, these dew shields are easily to attach and show almost no sign of wear after years.
