Mike I reckon you should experiment with 2 autoguiders if not an OAG.
Use the SBIG STX or the Italian Guys technique. Although he used an STL with self guiding plus a guide scope. Perhaps much the same as an OAG but there are times when an OAG isn't feasible due to lack of backfocus.
Have them out of phase with each other or one short and one long.
One on the dovetail one on your guide scope. The guide scope short and the one on your dovetail long.
Either guide 1 second exposures on your guide scope and 1 minute on the dovetail mounted one or guide scope 1 second and dovetail every say 10 seconds or experiment to find if there is an optimum timing.
Or mount a 2nd guider on your finderscope like the little orion 50mm mini guider package for around $319 at Bintel.
I plan on experimenting with autoguiding over the next several months and come up with improvements to this black art.
I have several ideas.
