AstroZap Dew Heater Strap for 9.25" Telescopes
Designed specifically for 9.25" Schmidt-Cassegrain telescopes, this AstroZap Dew Heater Strap is your first line of defense against dew-related image loss. Whether you're working under humid skies or imaging late into the night, this strap delivers low-wattage, even heating to your corrector plate, keeping your optics clear and your telescope performing at its best.
The strap wraps snugly around the OTA and is secured by a Velcro closure for quick, tool-free installation. Its fabric-backed construction offers durability and flexibility for field use, while the built-in nichrome heater element ensures consistent thermal performance without overheating.
A standard RCA plug allows the strap to connect to most 12V dew controllers (sold separately), giving you adjustable power to match the night’s moisture conditions. Whether you're visual observing or deep into an imaging session, this strap helps maintain contrast, clarity, and sharpness throughout the night.

Observing Tip:
The 9.25" SCT offers a unique sweet spot in contrast and resolution, but its corrector plate is no less vulnerable to dew than larger scopes. Power your heater strap on before dew starts to form, and pair it with a dew shield to extend battery life and maximize protection.
