Again, no attitude....
Thermal cycling would ALSO be an issue on the moon, more so than an orbital scope- so that doesnt work as an argument...
AS for : 336 hours vs. 90 minutes for a diurnal cycle.
well, again, that isnt relevant- the Hubble 'deep field 'was a MANY hour exposure- OBVIOUSLY orbital scopes can do long exposures....
As for Gyros, well- yeah orbital scopes need them, but a moon scope needs to track stars too- I still see NO reason why a moon based observatory is superior....
