I'm incredibly pleased to announce that we finally have tri-bahtinov masks available for the Celestron EdgeHD 11" SCTs. Just like all of our other masks, these are printed in ultra temperature and UV-resistant ASA. As a bonus (at least in my humble opinion) these are single-piece masks that do not require any assembly to use.
The downside to our single-piece design, however, is that it means we do not support Celestron telescopes in their F/2 FASTAR configurations. Hopefully someday we will come up with a solution to that we find acceptable, but until then we refuse to compromise on the integrity of the product.
In related news, keep your eyes on our regular bahtinov mask lineup! We've got a new unit in a customer's hands now, and barring any negative feedback you can expect to see that on the store in the coming weeks.
