Another great set Marc.
Be interesting to see what the 178 yields. I'm weighing up a few options myself for doing our sister planet a bit more justice.
I read about the aperture thing too and I think that must have more to do with the shorter exposure times you'd be getting from a bigger objective rather than greater resolution. Meaning if you get good seeing (not easy for UV), you could compansate to some large extent, as you could with even more sensitivity in UV. 8.5" ain't too bad for an 18 arcsec object whose angular size will basically double by late November while still presenting enough sunlit surface for clouds to be seen. Also, UV should increase your instrument's resolution thanks to the shorter wavelengths. IR does the opposite.
