My Laser Collimator
(How can you afford having none?)
General
My Laser collimator works very fine with either 1 1/4" or 2". It only works on "reflecting" optical systems as a newtonian or similar. For my yolo (a tilted-component-telescope) I need an additional flat mirror to reflect the light back.
How does it work? A small laser beam is pointed toward the secondary mirror, then toward the primary mirror, again to the secondary mirror and finally the beam spots the bottom of my collimator again.
If everything is aligned fine, I won't see any laser point at all, as it vanishes in the collimator (the original beam and the reflected one are absolutely parallel). If there is a laser point visible I need to re-align my primary and secondary mirror.
To help with the alignment I marked the center of my primary mirror with a small paper-ring with a hole and added a marking at the bottom of my collimator (see picture above) which represent the index of the screws I have to turn at my primary mirror in order to correct the alignment.
