Astrozap Dew Shield for Celestron CPC

This model is specifically engineered for the Celestron 9.25" CPC. While other Schmidt-Cassegrain telescopes share the same aperture, the mounting mechanism and tube diameter can vary, so it is best to stick to the model specifically listed for your telescope to ensure a secure fit.

Aluminum dew shields offer superior rigidity and durability compared to flexible plastic or felt options. They maintain their shape perfectly over time and provide a more robust barrier against stray light, though they are slightly heavier and less compact for travel.

No, this dew shield is designed for a friction fit or simple attachment depending on your specific setup, requiring no tools to mount. It slides securely onto the front cell of your telescope, making it easy to attach or remove in the field.
