This Farpoint FP358 dew shield for the Celestron 11-inch SCT is a precision-sized flexible dew shield for fork-mounted or bare-OTA configurations, also fitting 10-inch Dobsonians with matching tube diameters. It slips over the front of your OTA in seconds, slows radiative heat loss from the corrector plate, and keeps dew off your optics through the longest observing sessions.
Fits These Telescopes
Tube outer diameter: 12.05″ to 12.52″ (306–318 mm)
- Bare OTA: C11-XLT
- Fork-Mounted: CPC 1100 GPS, CPC Deluxe 1100 HD
- 10-Inch Dobsonians: Apertura 10″ Dobsonian, Zhumell Z10 Deluxe Dobsonian
Have a Celestron 11″ SCT on an Advanced VX, CGX, CGEM II, or CGX-L mount with a lower dovetail bar? Those need the notched version — see the FP359 Notched 11″ Dew Shield.
Why You Need a Dew Shield
The corrector plate on a Schmidt-Cassegrain telescope radiates heat directly into the cold night sky. Once its surface drops below the ambient dew point, moisture condenses on the optic, 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 corrector, dramatically slowing the rate of 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 corrector plate
- 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
