Astrozap Celestron NexStar Evolution 9.25 SCT Flexi-Heat

AstroZap Flexi-Heat® Heated Dew Shield – For Celestron NexStar Evolution 9.25" SCT

Built-In Dew Control and Glare Protection for Your Evolution 9.25"

AstroZap Flexi-Heat® dew shield is designed specifically for the Celestron NexStar Evolution 9.25" Schmidt-Cassegrain, combining the light-blocking and contrast-boosting benefits of a traditional dew shield with the power of a built-in heater strip to actively prevent dew formation on your corrector plate.

Constructed from lightweight but rugged ABS plastic, the dew shield wraps securely around the front cell of your SCT using a Velcro-style closure for quick setup. The felt-lined interior improves contrast by absorbing stray light while slowing radiative cooling of the corrector. And when dew threatens to form, the integrated heater strip gently warms the front glass to keep it clear—powered by a standard RCA plug compatible with most 12V dew controllers (sold separately).

This model is precision-fit for the Evolution 9.25" SCT without requiring a side notch.

Key Features:

• Custom Fit for NexStar Evolution 9.25" SCT: Secure fit without interfering with dovetail or fork arms

• Integrated Heater Strip: RCA plug connects to standard 12V dew controllers

• Dual Protection: Combines passive shielding with active dew prevention

• Felt-Lined Interior: Blocks stray light and improves visual and imaging contrast

• Flexible ABS Construction: Rolls up for storage, firm and stable when in use

• Velcro Closure: Easy installation—even in the dark

• Made in the USA: Quality construction from AstroZap

Compatibility:

Fits the Celestron NexStar Evolution 9.25" SCT. Not compatible with other 9.25" SCT configurations that require a side bar notch—see the AZ-809-E-SN for those models.

Observing Tip:

For maximum effectiveness, activate the Flexi-Heat system at the beginning of your session. Keeping your corrector plate slightly warmed from the start prevents dew buildup and reduces the chance of having to interrupt your imaging or observing to clear moisture.
