How is it that they stop at 60km?

Apparently you can see a cow in the middle distance but not the Moon. I suppose the Andromeda Galaxy is right out.

Perhaps it's the 'Power 1000% Lens' that's at fault … not enough magnification maybe.

Another plausible theory I've thought up over a Coopers Sparkling Ale: It's the red coating that stops any light coming from outside the atmosphere.

Yes, that must be it.

Thank goodness I'm smart enough to work out these technical matters.
