Hi Jason.
The inaccuracy of the Astrosystem as compared to the laser in your CN post is a very useful comparison and informative statement.

You state that, "Had your autocollimator been a laser collimator, it would have traced a circle with 1.25mm (10mm/8) radius on the primary mirror".

But, can you please explain, if the circle would have a 1.25mm radius, what does the (10mm/8) represent?

Thanks
Richard
