Description

A Bahtinov Mask made for the Celestron Edge HD 8" (CST) which also should work for the standard C8 version. With the Hyperstar 8 v4 installed the mask needs different slit sizes as well as a split design to allow for installation with cables and the front mounted camera. This design features a split that uses a diagonal cut to block light along the seam and a puzzle piece peg and hole design to align the two sides after installation. No hinges are used to allow for easier storage when not in use. Notches on the sides allow for clearance around the two screws on the telescope's edge.

I have included the Fusion (.f3d file) so edits can be made or makes for other sizes of telescopes.
