The primary rear mirror on the RH200 is adjustable for collimation by three bolts. These just simply are turned for any adjustment. No locking needed.

The rear plate is adjustable so that the sensor plane can be made orthogonal to the optic axis.

Unless these adjustments are done reiteratively by pixel peeping at the corners of test images any misalignment will appear as 'coma'.

These adjustments will be far easier with a sensor 36.8mm square.
