Mike, Hence my remark several posts ago about doing a site survey. I have no idea whether the observatory has done this, quantitatively. Never mind the mount, it is a separate issue.
As before this is a MUSEUM. Aesthetics and long-term lifecycle-cost count for a lot more than optical performance. Nobody in their right mind would do research at this site.
Mark - regarding the refractor vs the reflector argument the maths does support Mikes claim - and my own experience: given an APO refractor with good optics it does indeed take a reflector of 1.5X the aperture to match or do any better. Fast dobs optimised for faint fuzzies (not high power) are simply not relevant due to the light pollution. At the moment I am wrestling with Bessel functions in Excel to draw the graphs for you.
