Dew Shield for 6″ SCT Telescopes

This aluminium dew shield fits Celestron 6″ Schmidt-Cassegrain telescopes and ships with a protective cover cap. It prevents condensation on the corrector plate during cool, humid nights so imaging sessions can continue without interruption. The accessory is aimed at visual observers and astrophotographers who use a 6″ SCT and need reliable dew control. Buyers with larger or smaller aperture SCTs will need a different size shield.

Aluminium Construction and Package Details

The shield is made from aluminium and adds 4.70 pounds to the optical tube assembly. Its packaged dimensions are 16.19L x 13.59W x 13.19H inches. No active cooling or heating elements are included so power draw and fan noise are not factors. The cover cap protects the front aperture when the telescope is stored or transported.

Questions about this item

How do I install the dew shield on my 6″ SCT and what step do people often miss?

Slide the shield over the front cell until it seats against the corrector plate, then tighten the three thumbscrews evenly; the step many skip is checking that the cover cap threads engage before dew forms.

What maintenance or replacement will the aluminium dew shield and cover cap need later?

Wipe the interior with a lint-free cloth after each session to remove moisture; the cap threads may need a light dab of silicone grease annually, but the shield itself has no consumable parts.
