With alt/az mount you are limited in the exposure time to about 30 seconds, after which the field on the image will be rotated (unless you have a wedge). You can easily do planetary and lunary imaging, as well as imaging of bright DS objects at lower focal ratios (with SCT focal reducers f/3.3 or f/6.3)
In planetary section good and easy to use is DMK21 and other Imaging Source cameras, however it's beeing superseded by Point Grey Flea 3 (an probably Basler Ace) with new CCDs. The problem with Flea 3 is that it uses new 9-pin firewire (you would need probably some adapter) and it's quite new product. Such cameras can also be used to image DS objects (new cams especially) but they won't produce super images.
Dedicated astro-cameras like DSI III Pro can't do planetary efficiently, but they are very good at solar, lunar and DS imaging. For DS imaging you would have to keep the exposures very short like below 15-20 seconds which is doable with a focal reducer and bright targets like globular clusters
