Description

In 2008, Pavel Bahtinov, a Russian amateur telescope maker and astronomer, published an ingenious new way to easily 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 Bahtinov 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.

Finally, my stars are sharp and pinpoint instead of blurry blobs. The diffraction spike pattern on a bright star makes focusing so intuitive I got it perfect on my first try.

Penelope ★★★★★ Oct 20, 2026

I was struggling with soft stars in my deep-sky shots until I tried this mask—the cross-shaped diffraction pattern makes critical focus dead simple. It fits perfectly over my DSLR lens and cuts focusing time down to under a minute.

Abigail P. ★★★★★ Oct 19, 2026

The diffraction pattern snaps into focus so clearly that I nailed perfect focus on my first try with my DSLR. The cutouts are precise and the mask fits snugly over my lens without any wobble.
