Astrozap Focusing Cap w/ Built-In Bahtinov Focusing Mask for 10" Schmidt-Cassegrains and Similar Scopes

AstroZap Focusing Cap with Built-In Bahtinov Mask – 10" SCT and Similar OTAs

Achieving pinpoint focus is one of the most important—and often most frustrating—parts of any astrophotography or high-power visual session. The AstroZap Focusing Cap with Built-In Bahtinov Mask offers a simple, reliable solution by combining a precision Bahtinov focusing mask with a protective dust cap, purpose-built for 10" Schmidt-Cassegrain telescopes and similarly sized scopes.

With a sliding shutter mechanism built right into the cap, you’ll never need to fumble with separate focus masks in the dark again. Just slide the cover open, point your scope at a bright star, and use the distinctive diffraction spike pattern to guide your focus adjustments. When the central spike is perfectly centered between the outer two, you’re locked in and ready to go.

Once focus is achieved, close the shutter and the cap returns to full-time dust and moisture protection. Whether you’re working with a Celestron CPC 1000, Meade LX200 10", or another 10" SCT, this all-in-one design saves time, improves accuracy, and keeps your optics safe.

Features:

• Made for 10" Schmidt-Cassegrain telescopes and similar front cells

• Combines a protective cap with a built-in Bahtinov focusing mask

• Sliding shutter reveals or conceals the mask without removing the cap

• Precision-cut diffraction pattern helps you achieve perfect focus in seconds

• Durable black plastic design built for years of use in the field

• Ideal for both visual observers and imagers demanding sharp focus

Observing Tip:

With longer focal length SCTs, even a slight focus miss can result in soft planetary detail or bloated stars in your images. A built-in Bahtinov mask takes the guesswork out of the equation. And since it’s always attached, you’ll never leave it behind or wonder which bag it’s in.
