Hi Tim
I did try the OCAL Pro on my Mewlon 210 but when I then did a real world star test, it was way out of collimation, despite only making a few small adjustments to the Secondary Screws, just the pressure of a small tweak rather than a definite turn.
From my understanding, the OCAL device requires a centre spot on the secondary mirror (the primary mirror is not adjustable in the M210).
Have a look on CN

There are reports on RC's and DK's which suggest that the OCAL device is not suited to these scopes.
Cheers
