Hi Satoru, I would like to create a TriBahtinov-Bahtinov mask for a C8 (whose native focal length is 2000mm) with HyperStar, which produces an effective focal length of 400mm. By using your drawing app, the slits come out very thin (using a Bahtinov ratio of 100). But if I check "Use 3rd order spectrum", then the slits become quite wider. So my question is: what is the 3rd order spectrum? and should I use that option to draw the optimal TriBahtinov-Bahtinov mask for 400mm f/2 scope? Thank you! -Julio
Why do you ask for Bahtinov Factor?
You can obtain it this way:
Bahtinov Factor = Focal Length (mm) / Outer Diameter * 25.7
