TriBahtinov Mask for Collimation and Focus
A TriBahtinov mask operates under the same principle as the Bahtinov mask
for focusing and adds the ability to collimate scopes with collimatable
optics.
The design is based on Cytan's idea, documented on his Github site
here, and the sketch was made using Satoru Takagi's
Mask Generator.
The mask has a raised center for an easy grip and comes in three sections
that snap fit together and can be taken apart for easier storage (C5 is
one piece, 14" and larger are 6 sections).
FREE SHIPPING (USA) (1st Class)
Priority shipping available also. International shipping calculated at
checkout. Please see the shipping tab for more info.
Printed in durable, temperature tolerant PETG filament.
Please contact me if you are unsure if your scope is Fastar/Hyperstar
compatible.
Hyperstar Note: The C6, C8, C9.25, C11 and C14 TriBahtinov
Masks accommodate both Hyperstar and native Fastar/secondary mirror configurations.
The central hole is sized for the Hyperstar and the mask includes
a snap fit bushing to decrease the diameter for the Fastar ring.
