The 10" can resolve to 0.45 arcsec. The 152 to 0.76 arcsec. Hmmm...wonder why so many amateurs seem to have consistent sub-arcsec seeing when the professional observatories have such a hard time finding that
That is because amateurs and professionals define seeing in completely different ways. When amateurs can resolve a 0.5" double during moments of good seeing, they call the seeing 0.5", but such moments can happen on almost any night, if you wait long enough. When professionals call the seeing 0.5", then they mean that the diameter of the speckle seeing disk IN THE WORST MOMENTS are no larger than 0.5"!
