Overview
This tri-Bahtinov mask is made for the Celestron EdgeHD 8. We laser-cut it in Shropshire from 3 mm black cast acrylic with a polished finish.
How a tri-Bahtinov mask works
A tri-Bahtinov mask has three Bahtinov patterns set at 120° to each other. On a bright star, each pattern makes its own set of spikes. When all three middle spikes are centred, the telescope is in focus. If you can’t centre all three at once, the optics need collimating.
We can make a tri-Bahtinov mask for any telescope. Get in touch and we’ll talk through the design.
