I have now had the opportunity to use a laser/holographic collimator to
align some telescopes and other optical equipment. I have completed a
very long article on my experience with special attention to collimating
Cassegrain (and SCT) type telescopes.

The laser was loaned to me by Mr. H Glatter. It seems to work very well
and exactly as he describes in his instructions. It is a powerful tool
and does tell you a lot about your telescope is a quick an easy fashion.

Those interested in optical adjustments, collimation and the like, might
find my discussion interesting.

It is located in the Mechanical Concerns section on my web site.
