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.

Thank you for the detailed answer.

Try here  https://www.cloudyni...ment/?p=2742902

 

Click on the image in post #3, 4 and 5 and the animation should play.

 

(Edit: The old link titled "animation" in Jason's first post was the three individual animations listed above compiled in a single animation file.)

I just collimated my XT10 for the first time and this guide made it so easy. Thank you for putting it together for us. Love how 11 years later it's still one of the best heart.png

If I recall correctly, the animations in posts #3, 4, and 5 (click on the image to run the animation) show the same thing.
