Hi Davo,
Read my mind. I awoke this morning thinking what my next (and ultimate) scope should be. I keep wavering (which is just as well cos I can't afford either) between the C14 and the Mewlon 250.
The Mewlon 250 would be my dream scope, but its hard to part with $10K just for an OTA that's only marginally bigger than the C9.25. That said the advantages for an ultimate planetary scope are there. 1/20th wave optics. Built in electric secondary focussing so no mirro shift issues etc. Open tube so cool-down much easier than with an SCT. 10 inches also seems about the ideal size for resolution and portability, usability and performance with respect to seeing etc. Feel free to send me free money so I can indulge myself
.
But if it ain't the Mewlon 250 it will be the C14. It's cheaper, it's proven (best images I've seen) and has 14 inches of resolution on fine detail which is a big jump up from 9.25. The downside is the closed tube cool-down (perhaps a Lymax thingy) and biggness might put me off dragging it outside. I suspect it will be mre restrictive wrt the seeing conditions when it's worth using.
Ah, such pleasant and harmless ponderings.
cheers,
