The Astrozap focusing cap is a versatile, multi-purpose tool designed for astrophotographers and observers. Unlike standard Hartman or Bahtinov masks, it provides a quick "shutter-like" operation. Simply turn the wheel to the open position for precise focusing, and then close it to protect your telescope from dust or capture dark frames with a CCD or DSLR camera. Its lightweight aluminum construction and powder-coated black finish ensure durability and ease of use.
