Title: Bad collimation is a scope killer!
Review: 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.
