The relationship is not that simple.

One can also sample appropriately with a bigger 'scope....I also suspect my view (and Stan's) is vindicated by the professional push is toward ever larger aperture optical telescopes (e.g. 30 metres) rather than trying to telecompress 4 metre class instruments.

Guess we'll have to agree to disagree.
