HOTECH Advanced CT Laser Collimator Question
      #5207133 - 05/05/12 12:20 PM

When I first got interest in this product the alignment procedure required the lasers to be pointed at the 90 degree mounting screws. The 90 degree mounting screw method worked well for scopes that had mounting screws at a 90 degree angle. Ie. Mead SCTs. With Celestron there are no 90 degree angles, as an alternative there were tabs that you mounted at 90 angles on the outside of the scope. That now seems to have been replaced with using a defuser and aligning the returning donut of light on the laser holding face place.

My question: has the “donut of light” step eliminated the 90 degree mounting screw method, or am I missing something?

Thanks
Bart

It is just an alternative way of achieving the same goal. None of the methods is 100% accurate though. I use the donut method with my C14. The collimator did not come with paper tabs. The donut method is probably most subjective. I do get pretty good results when collimating my Hyperstar. The HOTECH Advanced CT Laser Collimator is a nice tool that every serious SCT owner should have. You can collimate secondary, Hyperstar, primary and center corrector. I wish the documentation was better though.

Agree 100%. I will say David has improved the documentation quite a bit as he's gone along, and that that in conjunction with the Youtube videos will now pretty much get anybody going without much heartburn.
