Buckeye Stargazer 3D-Printed Tri-Bahtinov Isolation Masks for Collimation and Focus

A Tri-Bahtinov mask aids in both focusing and collimating telescopes with collimatable optics.  When collimating, the Tri-Bahtinov presents (3) triple diffraction lines, which results in what looks like six separate sections of three lines.  

When paired with a  Buckeye Stargazer Tri-Bahtinov mask, these Tri-Bahtinov-Isolation masks isolate one section of the Tri-Bahtinov, which aids in determining which collimation screw to adjust.  

Printed in durable, temperature tolerant PETG filament.

Please note that prices shown are for the isolation mask only.

If you don't see your scope listed below Buckeye will be happy to design a mask to meet your needs.
