Meade Bahtinov Focusing Mask, 8"

Meade's Bahtinov Focusing Mask, 8" will fit a telescope diameter range between 215–260mm. Compatible with all 8" telescope models.

Take the guesswork out of precise focusing with Meade’s new Bahtinov Focusing Masks. This accessory is ideal for astro-imaging purposes. The Bahtinov Mask is placed over the front of the telescope and generates a distinctive diffraction pattern around stars. This diffraction pattern is clear and symmetrical when in focus. The pattern is very easy to see when focusing and makes the Bahtinov Mask intuitive for astro-imagers of all levels. Achieve perfect focus in mere seconds! Another benefit is this focusing method is very effective in turbulent seeing conditions when finding precise focus would be otherwise difficult. Sizes available for 8, 10 and 12" SCT and ACF telescopes, as well as any telescope that fits the diameter fit range listed for each size.
