The construction of this bino is very solid. The weight is not too much for hand-holding. The shaking caused by high magnification is not too much for hand-holding, but to get good sharp views, you need something like a tree or fence to support it. With the back of a chair to rest it on, you can see the 4 big moons of jupiter. They're like little points of light on either side. There are only 2 flaws with this pentax. First, there seems to be chromatic abberation that makes the focus not as sharp as it should be. Maybe with this high magnification and larger lens it should be expected, but i would not be surprised if the oberwerk 20x60 for $120 has better sharpness. Secondly, the lens caps have to be pulled out for you to see, but their click-stop is too far away. As a result, 25% of the field of view is lost. Gone. Wasted. A crying shame. The designers really screwed up. This is the main reason i do not recommend buying this bino. I sent an email to Pentax and they forwarded my email to "marketing". Maybe if they would forward this kind of feedback to the designers instead of "marketing" they would get a clue. Anyway, the oberwerk is probably better for a better price for distance views, but the oberwerk's short-focus distance is 60 feet (not too short!). One thing they did get right about this bino is the short focus (26 feet). The click-stop adoptor is not the most precise, but because the sharpness is not as good as you would hope, it doesn't make any difference. Keep in mind, at this higher magnification of 20x, your field of view is not as great and some vision is lost to shaking. If you're looking at nature stuff, a standard lower magnification of 10x like in a 10x50 will give you nicer (wider) views. The 20x magnification is more for gathering more information at a distance than for "experiencing" and enjoying what you're looking at. Another good thing about the 20x60 type bino is that it doesn't seem a whole lot larger than a 10x50 like a 20x80 which can be a real monster size. 20x60 is a good compromise between a 10x50 and 20x80. But for everyday use, my $110 Bushnell 8x42 (straight-type roof prism) is much much better and enjoyable, much smaller, and fantastically sharp with true color and perfect firmness in the focus, diopter, and eye width. And no field of view is lost from a stupid eyecup design like these. I'm not able to change my old rating to a 2.

edit: i like my new roof-prism 8x42 bushnells much better than these. I historically have hated bushnell, but comparing the 8x42 to these 20x60 pentax reveals a lot of color and sharpness flaws in the pentax. I can see detail only a little bit better with the huge pentax, if i have something to rest on.
