how much is enough
Paul posted a good question.
Provided you can get a bright enough guide star, I suspect there would be very little difference. Guide adaptively virtually none...corrections every 1/10th of a second can tame most systems (though a systematic drift will indeed show)
Sadly nature is rarely so kind. Plus if you want to drop narrow-band filter in place, expect corrections once every 10 seconds, maybe....
Given I get to image so rarely, I rather not leave things to chance in seeking excellent results but if you want to dabble and have a bit of fun the point is probably moot at best.
Cheers
Peter
