Rohan,

As Jeremy suggested "horses for courses", there is no scope that will "do it all".

If you want to wow an audience at outreach nights with the moon and planets as the targets, the C9.25 is the way to go.

But forget imaging DSO's with it, you will find an SCT frustrating and it will be outgunned by the faster, smaller refractor for which the cameras are most suited, given the seeing constraints affecting most.

For imaging there's not much point using a big heavy setup that can resolve 0.6 arcsec visually in conditions where the FWHM as recorded by the camera will be 1-2 arcsec or worse.

OTOH the planets in a short 100mm refractor... meh.
An f/15 refractor with perfect optics is another matter, but nobody makes these anymore, and no good for imaging.
