What is a Bahtinov Mask?
A Bahtinov mask is a device with many slots which can be placed between an optical assembly and a point source of light. When the light travelling from the point passes through the mask, diffraction occurs and the resulting image at the focal plane shows spikes of light which intersect. If the optical assembly in “in focus” then the spikes, of which there are usually three all intersect at a common point. When the optical assembly is out of focus then the spikes are seen to not intersect.

What Our Customers Say
“I have been using a Tri Bahtinov mask from Pro Astronomy for several years. The mask is extremely well made and I suspect it will last me many more years. The mask allows me to easily collimate and focus my telescope and has no doubt improved both my visual astronomy and astrophotography. I always recommend Pro Astronomy products to my friends”

Bespoke Bahtinov Masks
Each mask is optimised for a specific telescope where focal length, aperture and tube design is all taken into account. These masks also include our clamping system to ensure the mask stays secure while your telescope slews to a bright star.
Revolutionary Design
“The clamping mechanism on the Pro Astronomy Bahtinov masks is a real benefit to me. My last mask broke when it blew of the telescope in a gust of wind. This just can’t happen with the masks made by Pro Astronomy”
