This is Cuiv's Tri-Bhatinov mask he designed for use with a Celestron C6 and Hyperstar, but with a cutout to support the Celestron Dew Heater. This worked well, along with recentering the corrector plate, to significantly improve my collimation and star shapes for astrophotography. His model doesn't have a large enough cutout to sit flat with the dew heater installed, so I removed that portion of the exterior. Doesn't seem to cause any issues.

As a reference, this video is great:

Forgot to take a picture with it on the scope, will add one when I recollimate. 

If you're looking for a Bhatinov mask for a C6 at native focal length, I have another model here.
