Hi all,
for anyone who had an interest in this subject,I have just received a response from Celestron confirming that the ONLY thing that holds the main mirror cell in place on my Nexstar 127 Mak is the focuser knob - see below....
Hello Ron,
Thank you for contacting Celestron.
You are definitely correct. Removing the focus knob will unlock the primary holding cell and the mirror will be dislodged from the rear plate.

Unbelieveable but true !! I am not sure if the same applies to other versions of the Nexstar range and as I think the Skywatcher Mak range are made in the same factory,I guess it is the same for Skywatcher Maks.
So if you want to disassemble your Mak,OR just stand it up on the corrector plate/objective to do some adjustments,etc the message is:
DON'T REMOVE THE FOCUSER KNOB!!
