Review on 🌌 Astromania Alignment 1.25" Next Generation Laser Collimator with 2" Adaptor for Newtonian Telescopes: Precision and Versatility Combined by Robb Fillmore

When it arrived I was very excited to collimate my Newton which arrived slightly misaligned. As a perfectionist I wanted everything to be perfect so I ordered this and got to work. This forced me to make some pretty significant changes to the collimation. I pulled out the scope and it lost focus. General. Then I jumped on the internet and found out that one should check the collimation on the collimators before touching the scope because sometimes they get very confused. Mine was *very* off. There is a great video on YouTube on how to do this. Search "Collimate Laser Collimator" and this is a post by MikeyJ. You need to make a small device to hold the collimator in place before you can collimate it. And the rubber on the Allen screws really comes out terribly. Once you do that, you're in business. After much frustration, I learned that to adjust, you have to loosen one side and tighten the other. It took me most of the day to really figure out how to do it, but once I got close it was very easy to get the collimator perfectly aligned. I then used the Astronomy and Nature TV collimation videos to complete my telescope's collimation task and the world is back to normal.
