These are great binoc's all the way around but I use mine primarily for astronomical viewing. This size seems to me to be about perfect in terms of excellent light gathering and not being too heavy. I use them on a tripod and view the stars pretty much every evening when conditions permit. Thumbs up! (Posted on 4/11/12)
