- V block
- laser tool
Item is of excellent quality and works like a dream
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.
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!
As an 80 year old beginner, I was at first reluctant to purchase a reflector telescope because of the mystery of collimating. It sounded too exacting for me to complete. An amateur astronomer friend said it is an exacting process and you will want to use a lazer. I purchased this Orion Collimator for its price and use as seen in an online demo. This tool and instructions simplified my first collimation and my new reflector telescope had improved images. It is a must have in my tool box.
I was very happy with your crew that helped me out with my buy back and purchase of a new 10 inch light bridge. They were able to answer all questions which I had many. I do need some more accessory's and will be seeing you in the future.
