This Farpoint FP359 notched dew shield for the Celestron 11-inch SCT fits mounts with a CGE-style (Losmandy-style) bottom dovetail bar. The lower-dovetail clearance notch lets the shield seat flush over the corrector when the bottom dovetail would otherwise interfere. It slips on 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)

• Celestron 11″ SCT (lower dovetail): Advanced VX 11″ SCT, CGX 1100, CGEM II 1100, CGX-L 1100, CGX/CGX-L 1100 RASA V2

Have a Celestron 11″ SCT on a CPC fork mount or a bare C11-XLT OTA without a bottom dovetail bar? Those use the un-notched version — see the FP358 Dew Shield for Celestron 11″ SCT.

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
