Celestron 9.25 SCT Collimation Screws?

[BlueAstra]

I have a Celestron 9.25 SCT, but I can't see any collimation screws at the secondary mirror. The manual shows the screws clearly visible, but mine appear to be under cover, as shown in the photo. I know this mirror is removable to fit a Fastar system so I don't want to turn the wrong thing and see the mirror drop out. What precisely do you do to access the collimation screws and not remove the mirror?

just rotate the inner section (where the 3 finger holes are) to REVEAL the hidden screws

i do not mean the outer rim - this holds the whole secondary assembly to the front corrector glass plate

Hello there, was also unkown to me, though I have the C9.25 since almost 2 years, but they are there the screws, but are very well hidden.. just insert your finger in one of those 3 holes ( see picture ) and push them gently to side and you will see the screws..

OK I have it now. You gently rotate the top plastic cover with the Fastar plate on it. I think the lower finger holes are for removing the mirror.

I have just had the same problem, thanks for the info.
