The Astrozap focusing cap is a versatile and innovative tool designed for astrophotographers and visual observers alike. Unlike standard Hartman or Bahtinov masks, it offers a convenient "shutter-like" operation. Simply turn the wheel to the open position for focusing, and then close it to protect against dust or capture dark frames with your CCD or DSLR camera. Its lightweight aluminum construction and powder-coated black finish ensure durability and a sleek appearance.
