Package List: Reflector Telescope Collimator 2 Inch Adapter Sleeve English User Manual How to Use A collimator is a tool for adjusting the optical axis in which the pointer is attached to the center axis of an eyepiece-shaped tube so that the position and angle are exactly the same as the center axis of the tube. Since the position and orientation of the pointer is adjusted to precisely match the central axis of the eyepiece-like tube, it is possible to check whether the optical system is tilted correctly by following the light emitted from the collimator. It can be used to adjust the tilt of the secondary mirror and the primary mirror. First, adjust the tilt of the secondary mirror, and then adjust the tilt of the primary mirror. Adjust the optical axis with the optical axis adjustment eyepiece. If it appears to be aligned, the optical axis is aligned.
