Okay Collimator...

This collimator is pretty fair, but I later ordered the laser collimator, and discovered that my main mirror was a little bit off. If you're on a tight budget, like I was, this will do a good enough job. Otherwise, get the laser! :)
Works Well

I'm still new at collimation. I use this to get the secondary mirror aligned and then use a laser collimator for the final adjustments. They seem to work well together. My laser collimator has a self-centering adapter to remove focuser slop. I wish this did also so I could be sure that they were "seeing" the same thing.

It works fine. Takes a little getting used to it, but works like a charm.
Simple and cheap

This is a great item for the "regular guy" in astronomy. Sure there are more expensive options (laser) but if you're collimating your dobsonian with a friend there is no easier/cheaper way than this tool. I've lined up my 8 inch dob with this tool multiple times and it never fails. Love this piece. Makes up an essential part of my dobsonian toolkit.
Bad collimation is a scope killer!

This thing works. Right out of the box I was able to line up my mirrors in less that an hour to textbook perfect diffraction rings on a star. It is the first real collimation my scope has had since I got it.
I bought a cheap Dobsonian over twenty years ago. Didn't use it much, had a couple of cheap eyepieces. It made pretty good images compared to other scopes but I was never sure of the collimation.
Fast forward to today when the internet allows people to communicate with each other! Read the reviews on collimators and the articles on collimation. This device is a consistent favorite. Cheap and effective, it goes right to the front of my new and improved eyepiece collection.
