AstroZap Focusing Cap 130mm

When you want help focusing an image during a CCD or DSLR sessions turn the center knob to the "Open" position and reveal a trio of off-axis masks. This position allows the focusing cap to operate like a Bahtinov mask. The Astrozap Focus Cap doesn't stop there. Rotate the knob again to place the cap in the "Closed" position and take dark frames or use it as a dust cap.



Made from lightweight aluminum and powder-coated black, this Astrozap Focusing Cap is both strong and aesthetically pleasing. For installation: Three thumbscrews hold the Focusing Cap firmly in place.



The AstroZap Focusing Cap 130mm will fit 155mm-165mm optical tubes.

Ryan ★★★★★

Turned the center dial to "Open" during a DSLR session and those three off-axis masks snapped into place perfectly, making star focus a breeze. The build feels solid and the mechanism is smooth enough that I actually look forward to using it every clear night.

Charlotte D. ★★★★★

The rotating mask mechanism makes switching between focusing and imaging quicker than I expected. The off-axis masks really clean up the stars on my astrophotography captures. A solid upgrade for getting sharper shots without extra gear.

Sebastian ★★★★★

I was struggling to get crisp focus with my DSLR until I tried this cap—the center knob that reveals the off-axis masks is simple and clever. It’s now a permanent part of my imaging setup.
