I was noticing how bright Jupiter was last night, and decided to see how it looked through my wife's 10X30 Canon binoculars that I got her for bird watching. I've never planet watched (with visual aids) before and I was pleased that I could clearly see it was a planet, and I'm pretty sure I could see a couple of it's moons too, but I could not quite make out the cloud bands. The binoculars have IS and using that while leaning against the house I actually got a pretty clear & stable view. I then tried with my 20X spotting scope, but I couldn't find my good tripod and the cheap one I was using wouldn't let me press my eye right up to the scope, which it has to be at full zoom, so I gave up. What magnification does one need to see the bands of Jupiter?
