Astrozap AstroCap for 12" Schmidt Cassegrain Telescopes

Astrozap AstroCapAstrozap AstroCap


Unlike a simple Hartman or Bahtinov mask, the Astrozap focusing cap is a multi-purpose tool which allows for quick 'shutter-like' operation. Just turn the wheel on the Astrozap Focusing Cap to the open position for focusing, or turn it to the closed position to keep the dust out, or to image dark frames with your CCD or DSLR camera.

Astrozap AstroCap with Focusing Triangle Wheel


The Bahtinov focusing wheel can be easily removed and replaced with an off-axis wheel for off-axis viewing, or with an off-axis solar filter wheel for solar viewing on larger telescopes.
