Fair point Brian, maybe the OP should consider mounting the tube on an EQ6?
Optically, it shouldn’t be a challenge, it’s just the tracking and smoothness of motion. It’s something the OP should test.
FWIW, while the holy grail, of all theories solar system, favours scopes with small obstructions (or none at all), I’m very happy with my planetary images from my SCTs.
Add to that, the finest planetary images I’ve seen generally come from large SCTs and other scopes with significant obstructions.
There was a post a few years back over the other side where a chap had crunched the numbers and found that the obstruction of the average SCT resulted in contrast enhancement of certain feature scales in Jupiter’s atmosphere...
