Feature
●Wide applications: works with all types of telescopes, mirrors, refractors, for Dobsons, for Mak Cas and for SCT, all you need to do is measure the size of your telescopic tube and choose the suitable mask size.
●BAHTINOV MASKS: The mask eliminates the guesswork of focusing and even overcomes vision conditions to give your telescope the best focus quickly and easily.
●3 metal posts: the mask holds the telescopic tube gently and firmly with three metal posts. These metal posts come with scratch resistant silicone covers to protect the surface of your telescope. This prevents slipping while keeping the mask perfectly centred.
●Post installation and lightweight design: thanks to this 3-post holder, the mask remains centred and at the same time fits a wider range of telescopes. The Bahtinov Telescope Focus Mask is lightweight so you dont disturb the balance of the scope.
●Applicable size: the outer diameter of the Bahtinov mask supports the telescopic lens in the range of 60 to 90 mm.
