AstroZap Focusing Cap 130mm

AstroZap Focusing Cap 130mm


This focus cap is a multipurpose tool with a quick "shutter" like action that you will be glad to add to your collection. When you want to focus the image during sessions, turn the center knob to "open" to reveal a trio of off-axis masks. This position allows the focusing cap to operate the same as a simple Bahtinov mask. The Astrozap Focus Cap doesn't stop working there. Rotate the wheel once again to place the cap in the "closed" position, and either take dark frames or use it as you would any dust cap.

This Astrozap Focusing Cap is made from lightweight aluminum and powder-coated black; it is an excellent example of proud and great workmanship. For installation: three thumbscrews hold the Focusing Cap firmly in place; no tools or plastic plugs are needed.

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