Well I can find Jupiter's moons with my bins even after a glass or, ahem, two, of Chile's finest. You do need a really clear sky and you need to do that thing where you adjust the focus of each eye separately. Simply grabbing someone else's bins, unadjusted for your own eyes, just won't cut it. Those moons are minuscule pinpricks and you need good, sharp focus. After binoculars, the next best astronomical tool is a deck chair. No neck strain or aching back to give your hands the wobbles (don't forget your duffle coat though). And anything above 8x magnification is completely useless for hand-holding.
