I measured the secondary the other day, but just did again. I am getting 76mm on each one.
Is the green arrow the non-concentric part you are referring to? I thought that was just light leaking into the camera, as I has with difficulty holing it up to the tak scope. Maybe I have miss-identified the reflections I am seeing? But the green dot, is 100% the adaptor for the tak to screw into the moonlit, because of the smudge marks on it.
I have been looking for a concentric pattern between the Pink, and Blue parts. So the primary baffle and the secondary baffle(as I cant see the light annulus" through the tak scope.
Rotating the focuser will through the concentricity off in regards to each part.
