Vixen Collimating your VC200L or VMC200L - Manual (Page 4)

• Insert a centering eyepiece.
• Center the secondary holder in the field of view by moving the Focuser
adjustment screws (these are the push/pull screws on the back of the optical tube
closest to the focuser). Remember to always loosen one first before tightening the
other.
• When finished, the secondary mirror holder will be centered.
• You will then most likely need to collimate the Secondary if you move the
focuser.
When you have completed all the steps, we recommend that you Star Test your
telescope to verify collimation.
