This Farpoint FP338 dew shield for 127mm Maksutov-Cassegrain telescopes from Orion, Celestron, and Sky-Watcher is a precision-sized flexible dew shield. The Maksutov design’s front meniscus dews fast — this shield extends the tube to slow heat loss and keep your optics clear through the night.

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
