    In calibrating my AO-X (with STXL-11002), I am noticing that the axes are not orthogonal, as in the attached image.

    What does that indicate and is it something I should be looking into?

    It's not clear what that indicates, but the offset is so small it doesn't matter anyway.

    I agree with Doug, its so small, it is irrelevant.
    It could be an artifact of the mount reacting to the guiding calibration signals, lack of orthogonality anywhere in the system, cable drag, anything.
    So tiny, not worth worrying. You didn't mention the calibration time or which mount you are using.
    You might want to post that one over on the Software Bisque forum.
