Omegon 4" (115-135mm) dew shield

Suitable for telescopes with a circumference of 115-135mm. Measure the circumference of the telescope before ordering!

The dew shield prevents stray light from entering the telescope, and prevents fogging and freezing. Schmidt-Cassegrain telescopes are particularly affected by fogging, so this is an important addition to long observation nights! Can be folded evenly for storage.
