Hey Hazel. You will -- well, I do,anyway -- get about 20 or 30 seconds at a time of hand-held use from 15x70s before your arms get tired and start shaking too much. This is especially true the closer your target is to the zenith, since you've got to hold your arms out over your head.
You can use them for a quick look at something, but for extended viewing, you need a smaller binocular or a mount. Even a half-decent camera tripod with an L bracket should hold them perfectly well, though; they're light compared to a camera with a telephoto lens.
There's no complaining about what I've seen in them for that 20 or 30 seconds of good, steady viewing, though. Jupiter's disk can be made out at 15x, cloud bands and all, for example... Yesterday night I had my 15x70s (and a tripod) out looking at Jupiter for maybe two hours. It's quite enjoyable.
