Dobsonian

[AndyWB]

I compared a 10" SCT with my 10". There wasn't anything in it, really, at the same magnification.

I suspect that the author meant it was unsuitable because he doesn't like nudging - which is fair enough. Planetary is high power, so more nudging. Doesn't bother me, it might've bothered him. But you can get tracking/GOTO dobs, so you don't have to nudge - though that defeats part of the point of a dob in my mind - or you could put it on an Equatorial Platform, in which case it will happily track for an hour or so. (They ain't cheap, though).
