Astrozap Focusing Cap - 280mm-304mm

The Astrozap focusing cap is a multi-purpose tool with two positions. Use the open position for focusing and closed for dark frames.

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 to the open position for focusing, and then turn it again to the closed position to keep the dust out, or to image dark frames with your CCD or DSLR camera. Simply turn the thumbscrew to the open position, and turn to close.

Astrozap focusing caps are made from lightweight aluminum and powder-coated texture black.
