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 where you can see more details and images of this item in use.
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).
Sizes:
- TriBahtinov-C5: Celestron 5" SCTs
- TriBahtinov-C8-NF: Celestron 8" SCT (non-Fastar pre-1998)
- TriBahtinov-CClassic8: Celestron "Classic 8"
- TriBahtinov-C14-NF: Celestron 14" SCT (non-Fastar pre-1998)
- TriBahtinov-C6: Celestron 6" SCTs
- TriBahtinov-C8: Celestron 8" SCTs
- TriBahtinov-C9.25: Celestron 9.25" SCTs
- TriBahtinov-C9.25-NF: Celestron 9.25" (non-Fastar pre-1998)
- TriBahtinov-C11: Celestron 11" SCTs
- TriBahtinov-C14: Celestron 14" SCTs
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.
If you are unsure about which mask you need:
- Measure the inside diameter of the tube at the corrector and ensure that it is slightly larger than the Mask OD listed below, and
- Measure the outside diameter of the secondary housing and ensure that it is slightly smaller than the Mask ID listed below.
BuckeyeStargazer's items are made of PETG plastic and can handle temperatures of up to 80°C (175°F).
