Farpoint Carey Focus Mask – 2.5 Inch to 4.5 Inch Telescopes

Farpoint Carey Focus Mask – 2.5 Inch to 4.5 Inch Telescopes is an ingenious new way to easily focus a telescope.  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.  The method is simple, very intuitive, and the device has universally been named after the inventor: The “Carey Mask”.

Adjustable Carey focus mask for small telescopes. Adjust the grommets and pegs to fit telescopes with dew shield or tube from 2.5″ to 4.5″ in diameter.

Farpoint manufactures this “lifesaving” astrophotography tool out of virtually indestructible ABS plastic, which comes in two major types and in a range of sizes.
