Bahtinov Mask for Telescopes (Skywatcher, Celestron + More) - Achieve Perfect Focus
Achieve perfect focus with this 3D printed Bahtinov mask.
The Bahtinov mask consists of three separate grids positioned to create three angled diffraction spikes when pointed at a bright star. As you adjust the focus of your scope, the central spike moves across the star from one side to the other, where perfect focus is when it is in the center.
My products are 3D printed to order by me, and as a full time physics student I am often quite busy, so some items may be a little delayed depending on my schedule, most items are dispatched in 1-5 days.
The 3d printed items can be a bit delicate depending on the design, so need to be treated with care, and can occasionally very minor imperfections may be noticeable, but will not affect the item in any way. If you have any problems with an item once it arrives please let me know.
