Nice work Trevor, I knew it would not be long before you got started on Saturn. I am still hanging out to get a final SEB revival image.

Yes that is utter nonsense. Large scopes frequently are not at true ambient and are displaying boundary layer movment above the primary. That means that large scopes are accused of not performing well in poor seeing. Cooling a large mirror to ambient usually ensures that this problem disappears and the larger aperture will perform as good as smaller units if not better.
