I'm still testing my Tri-Bahtinov mask and here's a comparison between the Tri-Bahtinov mask and Airy disk diffraction patterns before and after using my LX200. I took these pictures pointing at Polaris on 28 May 2016.
Here's the as found Airy disk and Tri-Batinov patterns. My LX200 is badly collimated
And here it is after correction
Anyway, I think the Tri-Bahtinov mask seems to work
I will be writing a python script to generate arbitrary sized Tri-Bahtinov masks and that will be uploaded to my github site https://github.com/c...299/tribahtinov
