Farpoint Bahtinov Mask 8.5"-10.5"

In 2008 an amateur telescope maker and astronomer published an ingenious new way to easily focus your DSLR, webcam or CCD camera for taking astro-photos. The method is simple, very intuitive and the device has universally been named after the inventor. The Bahtinov Mask. 

Farpoint manufactures this *LIFESAVING* astrophotography tool out of virtually indestructible ABS plastic and comes in two major types and in a range of sizes. The mask pictured below left is a general purpose mask designed to fit refractors and Newtonian telescopes. The mask pictured below right is designed to fit Schmidt-Cassegrain telescopes. Both types of mask are available in a range of sizes to cover your needs.
