Astrozap Focusing Cap w/ Built-In Bahtinov Focusing Mask for 14" Schmidt-Cassegrains and Similar Scopes

AstroZap Focusing Cap with Built-In Bahtinov Mask – 14" SCT and Similar OTAs

Fine focus can make or break your imaging session—especially at long focal lengths where critical focus is razor thin. The AstroZap Focusing Cap with Built-In Bahtinov Mask is the smart, time-saving solution for precisely focusing your 14" Schmidt-Cassegrain or similarly sized telescope.

This innovative two-in-one design combines a standard dust cap with an integrated Bahtinov focusing mask, letting you go from storage to sharp focus without ever removing the cap. When you're ready to focus, simply slide the internal shutter to reveal the Bahtinov mask—no need to fumble with separate accessories in the dark.

The Bahtinov pattern etched into the cap creates a unique diffraction spike pattern around bright stars. By centering the central spike between the outer two, you can dial in tack-sharp focus in seconds, whether you're using a DSLR, planetary camera, or dedicated astro-imager.

Once focus is set, slide the shutter closed and you're back to having a protective dust cap in place. It’s a clean, compact, and field-friendly design built for repeat use.

Features:

• Designed for 14" Schmidt-Cassegrain telescopes and similar OTA sizes

• Combines a standard dust cap with a built-in Bahtinov focusing mask

• Sliding shutter reveals or hides the mask with no need to remove the cap

• Enables quick, ultra-precise focusing using diffraction spike alignment

• Durable black plastic construction built for years of field use

• Ideal for visual observers and astrophotographers alike

Observing Tip:

If you're imaging with a 14" SCT, you’re already pushing magnification and depth—don’t let your focus be the weakest link. A Bahtinov mask gives you instant visual confirmation that your focus is perfect, even in variable seeing or on faint targets. Having it built into the cap means it’s always at hand when you need it, and never in the way when you don’t.
