The first question is whether you are a primarily visual observer, or aiming at photography.

If the former, I'd suggest either a 10" dobsonian, C8 (small and light) or C11 (aperture rules, but its a big heavy beast).

If the latter, stick to small refractors upto 100mm to start with - and forget SCTs, they are a whole world of pain. While it is possible, its far from easy and you have a lot to learn.

Disagree re the C9.25 for planetary BTW, the slow primary means a big fat secondary obstruction to achieve f/10 and the result is a scope that is not ideal for high power (planets), and not good for low power/wide field stuff. And SCT's don't achieve much better than 0.90 strehl on DPAC tests.

If you want a serious lunary and planetary scope find a big Maksutov f/13 ... f/15 with small central obstruction and high strehl (0.95 or better).

These are like unicorns - they are legendary, very few have seen one, and a very lucky few own one.
