The critical moment today - fitting the F8 200mm GSO newt. The OTA is 900mm long BUT when fitted out with ASI focuser , CCD etc, and when tilting it to 27.1 degrees (my latitude) you change the dynamics a lot - enough certainly to swallow up what I thought was my clearance margin. In short, I have to cut away some of the internal bracing I installed. And to add insult to injury, cutting off the roof meant the structural integrity of the base was seriously compromised. So I am now installing extra anchor bolts, and bracings. And I nearly forgot - the scope sits too tall in the mount to allow it to clear the roof at the CWD home position. No big deal. Just a nuisance.
