C11 Mechanical Alignment & Collimation

Tube Squaring and Sanding


The tube mechanical axis needs to coincide with the baffle tube axis to ensure that the various components (primary, corrector and secondary) are centered as close as possible mechanically in the CF tube in respect to the baffle tube.

So the very first thing we need to do is make sure the CF tube ends are cut square.

Once the corrector cell is fitted and centered in the front we need to take care of the other end which will be bolted into the primary cell casting.
If the back end of the carbon fibre tube is off square by even one degree, it will have catastrophic effects on the centering of the corrector plate, secondary mirror, and hyperstar on the optical axis of the scope. Conversely, the front end can be quite a longer way off-square before it affects the centering of the other components.
