About this item

Bahtinov focus mask for telescope 80mm in diameter.

The Bahtinov mask is a device used to focus small astronomical telescopes accurately.
Although masks have long been used as focusing aids, the distinctive pattern was invented by Russian amateur astrophotographer Pavel Bahtinov

The Bahtinov or focusing mask is a brilliant aid to get a perfect focus. When the telescope is pointed toward a bright star, the mask generates the typical pattern that makes the focusing procedure easy. Adjust the focus of your telescope till you will see a symmetrical pattern.

Masks now feature 3 holes which can be attached with 3 screws to prevent the mask from falling off the front of the telescope.
It will take less than 1 minute to achieve perfect focus with your new mask and will mean you spend more time imaging photons rather than focusing them
Light weight so you wont upset the balance on your scope.
