Here in Oregon we also have something called "The Three Sisters". But ours are a bit bigger: http://vulcan.wr.usgs.gov/Imgs/Jpg/Sisters/Images/Sisters85_aerial_three_sisters_oregon_09-85_med.jpg South Sister is the tallest, at 3159 meters.

It looked very different in Hawaii. Heh, I looked at that picture for 5 minutes trying to figure out how your moon ended up on the bottom, then I remembered I'm north of the equator.

I doubt that the celestial bodies in SE Qld are physically any large than Eastern NSW, but the planets look very small by comparison in your photograph. phrantic - I suspect my own photos of the Three Sisters could almost be superimposed over Dan's, too. I took quite a few from the viewing platform at Echo Point in various spots, so I'm sure that one was close. Hey Dan, does that painted fellow still play his didgeridoo for all the tourists? I got quite a chuckle out of seeing all the foreigners 'oohing' and 'aahhing' over the sight. It's funny how deceptively large they looked in real life.

My best photograph from my Qld-to-Vic roadtrip of the Sisters could almost be overlaid on that one. I've stood, I think, precisely where you tripod is sitting in that Three Sister's photograph.

I can spot them with a pair of 10x25s, so I'm a bit disappointed that a Digital SLR can't pick them up, especially as I just splashed out on an EOS 450D:(. I don't see any moons round Jupiter?
