Collimating the laser collimator. Without the secondary mirror I pointed the telescope to a white wall, then I rotated the laser and verified that the beam always hit the same point. |

Centering the corrector plate and the secondary mirror. The laser beam hit out the little circle, so I moved the plate until the beam hit the center, then I locked the plate. |

The secondary mirror and the corrector plate are centered, the laser beam hit the center of the circle, but the secondary mirror seems to be a little out of collimation. |

Now the secondary mirror should be collimated, the laser beam return back to the source, but a star test is needed to verify the collimation. Test soon.. |
