Quote:Eddgie, maybe this will help your explanations. I'm a CAD operator in real life, and I used CAD to do a rough simulation of the diffraction effects involved in our observations of Io. I humbly submit it here for discussion. This models an 8" telescope with no CO, giving an Airy disc of 0.68". I've laid multiple airy discs over a grid laid on the face of "Io", with equatorial region discs shown bright, and polar discs shown darker.It's a good likeness to what I observed, allowing for my crude simulation.J
