It's actually annoying me, so yes, very confident a scope like your 16" or a smaller pixel camera on my scope, would definitely excel at high resolution imaging at Eagleview, the extra sampling could handle some more decon as well.

Hi Mike,
yes - with Paul's RCOS 16" at FL = 3,414 mm and
ZWO2600MM Pro pixel size of 3.76 microns
his arc-sec per pixel ratio is: 0.23 arc seconds.

With your telescope -
Just using the ideas of the Nyquist sampling theorem if you
ever got sub 1 arc second seeing you would need a minimum of
0.5 arc seconds per pixel to properly measure it.
So any measurement below 2 x 0.84"/pixel or 1.68 arc seconds seeing
is probably not accurate?
Paul's telescope could take full advantage of the seeing at your wonderful location.
Can anyone please correct me if I'm wrong?
cheers
Allan
