Star of med brightness on the ecliptic is part of it but best sample rate is .1 to 1s according to some sources but would not this run the risk of chasing the seeing? Could a pec train be done on an artificial star?
I run Guidedog a 2 seconds anyway, so 'seeing' errors would be minimalised.

As far as an artificial star goes, how would you get an artificial star to track at exact siderial speed. Sounds like a no go.
