Moisture Control

Moisture is a menace to fine optics. We carry quality dew shields of every size to keep your optical equipment clean and dry. We also have desiccant caps with silica gel inserts for closed tube telescopes, keeping the inside of your telescope comfortably dry. And we stock reusable dry packs to store in your airtight cases for moisture control.
