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 ED 80 will fit 101mm-110mm optical tubes.

Emily ★★★★★

Finally found a focusing cap that actually works with my DSLR setup—the three off-axis masks make centering stars quick and painless. The center knob is smooth and stays put once you select your mask position.

Grace ★★★★★

The mask trio design on this cap makes focusing so much more precise—I no longer second-guess my adjustments like with basic caps. Turn the knob to open and you instantly see three clear off-axis views, which saves time during sessions. Solid buy for my ED 80.

Emma ★★★★★

I was struggling to get sharp focus with my DSLR, but the center knob switch to "Open" instantly gave me those three off-axis masks to work with. It's a simple solution that finally lets me dial in my ED 80 clearly.
