    Default 2-axis / 3-axis kinematic mount

    I'm confused about something.

    Could someone please explain to me what the 'third axis' is that you can adjust with 3-axis kinematic mounts?

    Thanks in advance!

    Hi FourDee,

    With the two-adjustment mount you can adjust the angle in two directions, but the center of rotation is not the center of the mirror, so the position of the mirror is changing too. If you have a three-adjustment mount, you can adjust the angle without changing the position of the mirror, or if you wind all three adjustment equally, you can adjust the position of the mirror without changing the angle.

    Kind regards,
