Bahtinov Masks

A Bahtinov mask is used to find critical focus for just about any telescope.  

I will custom design a mask to fit your needs and which is tailored to the scope's focal length.  Currently available models are listed below.   Masks 6" and smaller are a one piece design.  Masks greater than 6" are a sturdy two or four piece snap fit design. 

Please note that I recommend my TriBahtinov Masks for SCTs, RCs, CCs, Newts or other compound scopes which adds the ability to collimate as well as focus.  

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


Priority shipping available also. International shipping calculated at checkout. Please see the shipping tab for more info.

Printed in durable, temperature tolerant PETG filament.
