A simply brilliant device. I was introduced to this laser collimator the other night when we were collimating Paul Shopiss' 12" binocular telescope.
I've never performed a full collimation so quickly and easily. It literally took 15 seconds per side once the collimator was inserted into the focuser. Paul has thumbscrew secondary adjuster screws as well as knobs on the primary adjusters, so there was no fiddling with screwdrivers or allen keys.
1) Firstly you insert the unit into the focuser. Remove the concave barlow attachment to expose the end of the laser and switch it on. A beam hits the secondary and bounces down to the primary. You adjust the secondary until the beam hits the centre mark on the primary.
2) Then place the barlow attachment back on the front of the unit. It acts as a projector screen and shows the return image from the centre dot on the primary. All you now do is adjust the primary's collimation knobs until the centre dots image hits the centre of the screen.
Done! It literally took seconds and gave great collimation. When you have two optics trains to set up each night it'll be a real bonus. Normal laser collimators don't do anywhere near as good a job I don't think - and certainly no where near as fast.
US$109 plus delivery ex Colorado USA.

I'm in no way affiliated with this crew - just a really satisfied customer.
