For the first time in my ownership of my LS 8, I've discovered that the unit that holds the secondary mirror actually rotates within the corrector plate. 


I don't know whether this is usual for the LS series of scopes; does anyone else have a 'rotating' secondary? On a couple of other forums there is discussion about whether the alignment of the secondary is critical - it is generally reported that for Celestron scopes it is critical, but it's less certain for Meade scopes. 


Does anyone fancy seeing if their LS8 secondary rotates? 


Please report back

I don't think it should.  If it is like the older SCTs there is a retaining ring that screws on to hold the secondary in place.  I suggest that you call customer support and talk to them about tightening it back up.  You may be able to pull on the outside end of the secondary and turn it the direction like you are screwing a screw in and see if it will get tight.  When done, you will probably have to adjust collimation a little.
