Go, Keck!

Now... anybody have some numbers on what kind of effective "seeing"
they're winding up with? There were some references in the image
captions to "resolution" in the milliarcseconds, but I don't know
if that's quite the same thing.

On the (comparably) small telescope I sometimes operate across the summit
from Keck, "seeing" ranges between roughly 0.3 and 1.3 (yeah, I know)
arcseconds. I've heard that with AO and the laser guide stars, the
decimal would be moving over a place or two... anyone know?
