Farpoint Dew Shield - Orion 180 Mak

This Farpoint FP344 dew shield for 180mm Maksutov-Cassegrain telescopes and large 150-165mm APO refractors is a precision-sized flexible dew shield. It slips over the front of your OTA in seconds, slows radiative heat loss from the front optic, and keeps dew off your meniscus or lens through the longest observing sessions. Fits These Telescopes Tube outer diameter: 8.42″ to 8.90″ (214–226 mm) 180mm Maksutov-Cassegrain: Orion 180 Mak, Sky-Watcher Skymax 180 Maksutov-Cassegrain Large APO Refractors: Explore Scientific 152mm f/8 ED APO Triplet, Explore Scientific ED165 FPL53 Triplet Why You Need a Dew Shield The front of your telescope radiates heat directly into the cold night sky. Once the front optic drops below the ambient dew point, moisture condenses on it — blurring your view and ending your observing session. A dew shield extends the tube to create a buffer of still air in front of the optic, dramatically slowing heat loss. The Farpoint flexible dew shield is the simplest and most effective dew prevention tool you can own — no power required, no batteries, no warming straps. Just slip it on and observe. Built to Last ABS polymer construction — durable, UV resistant, virtually indestructible Black felt lining — kills stray light reflections, won’t scratch the front optic Hook-and-loop closure — wraps tightly, removes in seconds, stores flat Precision-sized to the casting — not a generic one-size tube Proudly made in the USA Not Sure If This Fits Your Telescope?
