I'm sure Jason has an article planned.Jason, I think you should start the "now really concise, I promise" autocollimator thread
.
We can discuss it here after it's released!

(Has there ever been a concise thread about autocollimators?)

Yes....a question:- It seems to me that the suggestion is that a 2" AC would be more useful than a 1.25" AC. In order to clearly identify the reflections, the wider AC mirror is better? True?

Seems to combine the benefits of a triangle and a ring--and should work well with a laser diffraction pattern too....I am still interested to hear your opinion about the following center spot shape.

For that last comment:Erick, make sure to report back
To those who are planning to buy an autocollimator, make sure to have reviewed my earlier post
Your expectation from an autocollimator should be high. After all, the autocollimator is meant to provide that last extra precision above and beyond your other collimation tools. You might not get that last extra precision with an average autocollimator. But you will get that last extra precision with a high quality autocollimator. Of course, your scope mechanics need to be stable enough to take advantage of that extra precision.

Of course, you could use the smaller CatsEye triangle, which should allow the various signatures to be seen with a smaller AC tilt. It's a matter of scale...and readability......photo (A) is not what you would really see – I lied. What you will see is represented by photo (B)...

The "smaller tilt" requirement means that you need to bring collimation close to perfection using other collimation tools before the 1.25" AC can be used. The 2" AC is not as demanding.which should allow the various signatures to be seen with a smaller AC tilt

That's why I mentioned readability...(and followed with a "thumbs down")The "smaller tilt" requirement means that you need to bring collimation close to perfection using other collimation tools before the 1.25" AC can be used.

Jason, thanks for posting the reference page. As soon as I get a chance to set up the 22, I'll give the XLK+CAM another run with special attention to offset lighting and implementing negative CAE. I'll see if the read issues persist, or if my XLK+CAM experience was just one too many reiterations and not enough patience on my part.Vic, with respect to iterations between P+2 and CAM stacks, if you refer to the following page starting from post #3098491 to post #3098519 (6 posts), I explain how to cut down on the number of iterations.

So, once again, would I tell a noticeable difference following Jason's instructions?

This is such fun to watch - the leading edge of new developments.
I wait with interest, Jason.
