Colin, don't waste your time unless you are going after medium resolution lunar imaging. The large central obstruction (50%, linear) destroys sub arc second contrast. That is why you won't find cutting edge planetary images made with RCs or CDKs.

For imaging the planet's I found the ASI 294 MC camera to be ideal, and I use the non-cooled version for planetary, because I am realtime stacking and aligning with Sharpcap and long subs for planetary are unnecessary.
Don't make It harder than it needs to be. My time spent with an SCT was a waste, constant frustration, with mirror flop, condensation problems, etc. I fail to see the attraction of SCTs for anything to do with Astronomy, except maybe they are easy to transport..

Newtonians can perform well as planetary imagers but they are hard to tame. SCTs, as you say, have problems, but some of the best planetary images are taken with C14s.
