Hi Eric!
Thankyou for the tips, very much appreciated.

Nope, no movement at all, it's nice and sturdy.
I've done as you suggested re: the lock locking bolts & screws on the primary. I have been attempting to collimate at a 45 degree angle as it was suggested in a video I watched to avoid dropping things on the primary (good advice)! This afternoon's effort went fairly well as I collimated outside and there was more light than the previous night indoors. I only have one problem - the black dot from my cheshire is not lined up exactly with the annulus in the centre of the primary mirror. Not sure if this is a big problem or not but I physically could not get it any closer without overtightening one screw, much to my frustration.
Cheers
Wade
