William Optics Bahtinov Mask w/ Diffraction Spikes for 243mm-308mm Telescopes
This Bahtinov Mask from William Optics utilizes the new optical acrylic sheet to offer 92% of light transmission. This gives users the highest and brightest diffraction spikes!
Using the acrylic sheet, instead of the traditional metal, means that this Bahtinov Mask makes the spikes three times brighter.
This Bahtinov mask is meant to work with telescopes that have a diameter of 243mm to 308mm.
