Orion LaserMate Deluxe II Laser, a very useful tool....but....
upon using this laser tool I found a confounding issue of differing collimation while it was in various rotated positions. I then rotated the laser while looking at the primary spot and viewed a circular movement the size of a nickel so I made a V block and tested it on a wall about 20' away and sure enough it showed the same circular deviation. I then removed the label (don't do this if you intend to return it, this may void any warranty) and adjusted one of the allen key screws and brought the beam to rotational center. I then tried it on the scope and it worked perfectly, I also used it to Barlow collimated for a more accurate collimation, so it's a very good tool if it's aligned correctly hence 4 stars.
Orion LaserMate II, Easy to use Collimator from Orion
Love this tool which make's collimating a Newt,under 5 minutes. Make sure it sits perpendicular and vertical to the tube allowing gravity to hold it in place. Adjust secondary mirror, first!, then move on to Prime IF required. Repeat, for finer adjustments. For first time buyer's, you won't go wrong with OPT...One of the best!!!! Highly recommend.
This is the first time I collumated a telescope. This made it super easy. A must have tool!
