Hi Robert
If you are going to specialise in hi-res Lunar and Planetary imaging, it might be worth considering a more specialised OTA, such as the Mewlon's from Takahashi? Reviews do tend to indicate "refractor like" performance?
I was eyeballing the other night with the C9.25 and the Vixen 4" and the stars just looked fantastic in the Vixen 4", with beautifully formed diffraction rings, whereas the C9.25 looked a little ragged at the edges. The Trapezium looked gorgeous, with diamond point like stars in the Vixen, whereas in the C9.25, they were a little softer and not as distinct.
Cheers
Dennis
EDIT - I mean the larger Mewlon's as I know you have the 180.
