About this product

BuckeyeStargazer TriBahtinov Mask

A TriBahtinov mask operates under the same principle as the Bahtinov mask for focusing and adds the ability to collimate scopes with collimataeble optics. 

The design is based on Cytan's idea, documented on his Github site here. The sketch was made using Satoru Takagi's Mask Generator.

The mask has a raised centre 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 six sections).

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.

Please Note: These Tri-Bahtinovs have a keyed connection 'tab' between each segment that is joined together.
                     Please check the orientation of the connectors and ensure you push them together correctly and do not force them from the incorrect side/angle.
