Fortunately, the animations on posts #3, 4 and 5 still work if you click on the picture (checked with MacOS Safari).

I stumbled on to the same procedure Jason D. described quite by accident after suffering through the headaches of learning and understanding collimation (to the limited degree that I do) and I have to say it is the best way for those of us that are not experts in optics to achieve decent collimation.
It was the source of major frustration but I slowly put the pieces together on my own only to find the solution spelled out here - after finally getting my scope collimated to a reasonable degree! I checked this forum a few years ago and came across all sorts of posts on collimation that were far to technical and confusing for me so I just forged ahead on my own until I had a working process.
Jason's procedure should be placed in a downloadable pdf for people to easily find without having to read through 20 pages - most will bail out before they get to Jason's post would be my guess. Jason's 6 step process is the easiest for beginners in my opinion.
Collimation can turn normal people into mental patients in no time.
