In 2009, George Carey, an amateur telescope maker and astronomer from the UK, published a modification of previous focus mask designs to make a much more sensitive version of the device. This focus mask allows you quickly, easily and precisely focus your DSLR camera, webcam or CCD camera for astrophotography. The method is simple, very intuitive, and the device has universally been named after the inventor: The "Carey Mask".
Farpoint manufactures this great astrophotography tool out of virtually indestructible ABS plastic, which comes in two major types and in a range of sizes. We carry masks designed to fit both refractors and Newtonian telescopes, as well as SCTs.
