i guess thats how an experimentalist talks John....
By the way, i think one could automatize the collimation process somewhat with the help of kuka robots.
One needs a thing like this hotech advanced collimator and change the visual back of the scts such that it can be tilted.
The robots then fix the scope on its prism rail, remove the secondary, insert a reflector mirror in the visual back and align the target plate of the hotech like mechanism and the visual back of the scope. They do this grabbing the necessary tilting screws of the visual back and the tilting screws of the target plate.
The system could measure alignment by some ccd measurement of the laser positions of the hotech in position 1 (the crosses at the target and visual back should be centered. of course the lasers should be more precise than in this hotech for that).
Then the lasers of the hotech are set to position 2. The robots insert the secondary and rotate it. Meanwhile the robots manipulate the collimation screws of the secondary until the laser dot in the visual back does not wiggle around during rotation. That way the robots "zero out the knobs" of the secondary.
Then the robots center the corrector plate until the lasers dot in the visual back is in the the center.
Finally the robots fix everything.
That way the secondary, visual back and primary are aligned, but in a way that every surface is horizontal on each other and the thing is centered.
In a second step, the telescope is brought to a phase cam interferometer and it is aligned. this alignment to the interferometer may also work with the help of robots via lasers.
Then the robots grab the secondary and corrector plate and rotate them a bit. After the rotation, they fix everything and move their arms away. Now one makes an image with the phase cam.
Then the robots loose the screws and rotate the secondary and the corrector plate again and one makes another measurement. Since the robots have zeroed out the knobs of the secondary, the scope remains in collimation if one rotates the secondary and corrector.
If the correct angle of the corrector and secondary is found after a few rotations, the robots fix all the screws with locktite and the scope goes to a short visual inspection by a human.
Would this work as an automated process like this?
If so, then one would only need a few optics engineers who make a last visual inspection and one would need people who look after the robots...
At least this is how car motors are assembled in germany. This process also has few tolerances and there is not much to be done by imprecise humans.
I do however, not know if that would work to assemble a Celestron telescope automatically....
