New William Optics bahtinov focusing mask made of acrylic sheet which maximises light transmission for ease of use.
The new Optical acrylic sheet offers 92% of light transmission that gave you the highest and brightest diffraction Spikes for Focusing !
It’s approx 3 times brighter than a traditional metal mask.
Got one of these to use with my Stellamira 90mm Triplet. It comes really well packaged, easy to assemble and fit's really well on the scope. Gives excellent diffraction spikes.
Brilliant piece of kit.Much better than a standard mask.Large and brighter defraction spikes make focusing simple.
