A very social session today... we worked on collimation of different telescopes... aligning the optics so that they show beautiful pinpoint stars.
That's a great way to think about it! Fingers crossed we can banish the triangular stars on the VC200L forever.
Here is what Wikipedia has to say about the collimation of a Dall-Kirkham telescope.
"Another advantage of either the basic Dall-Kirkham or the Modified Dall-Kirkham design is that collimation of the convex spherical secondary mirror with respect to the optical axis of the primary mirror is almost trivial, because there is no single defined axis of a sphere. Any line that runs through the center of the sphere can be an axis." Our mileage obviously varied on that one. :)
Looks a bit too casual to me. :) You must have been the only one working on the collimation!
