Ahh, I love binoculars - mainly for stargazing. But also for wildlife. I go walking to dark places to get good stars, galaxies, nebula, clusters, etc.
The best light weight binocs I have are Minolta 8x23, about 9oz. I recommend shopping by looking out the store window at a bright sunlit scene with all the binocs they have. Pick the ones with the best true color and sharpest images.
But if I'm going to bother carrying binocs at all, my favorite are Canon 10x30 IS. These are heavy, 1' 7", without strap or case, but they are "image stabilized". Push the button and all jiggle goes away. They really work, especially for stars, and give a very stable vibration free image. They use AA batteries. They are also expensive - about $325, but worth it if you love looking at things.
Otherwise to get rid of vibration, hold binocs against a tree, or tight against your trekking pole. I have a tripod adaptor that I screw into my pole to hold even bigger binocs steady.
I take off all straps and case and use only zip lock bag for protection when hiking. I tape a bottle cap over the IS button to make sure it doesn't turn on in my pack.
