Quote: In image sets when using 10-second autoguider exposures RMS is usually about 0.05 arc-secs on good nights. If you want a minimum RMS number to shoot for that is probably close to it. And it is obtainable without too much effort on a good mount with a good PEC curve and tracking rate modeling.
