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 for ETX 125 will fit 136mm-146mm optical tubes.

Olivia J. ★★★★★

Turning the center knob to "Open" and watching those three off-axis masks line up was oddly satisfying on my first DSLR session. It's made focusing on brighter stars so much quicker, and the masks cut down the halos almost completely.

Christopher L. ★★★★★

Finally, a focusing cap that actually works for my DSLR setup—the three off-axis masks in the open position make dialing in sharp stars a breeze on my ETX 125.

Ella ★★★★★

Finally got crisp focus with my DSLR on the ETX 125; twisting the center knob to open the off-axis masks was a game changer. Takes some practice to center the target, but the improvement in sharpness is immediate.
