Your fairly locked into tight sub 2 sec guiding with no backlash (and at short FL imaging though), could be tricky, I hope your on the right track overall.

I believe I am...
As my prime interest is photometry and (as a next step) spectroscopy, a relatively short FL (up to 1000mm) is quite OK for the purpose [I am already using MTO1100-A (Maksutov cassegrain) for this, and 30 sec sub-exposures without guiding are quite possible even as the things are at the moment (with ~30% reject, due to aforementioned jitter].
