Excerpt: The size of this bino is probably the largest still possible to use without a tripod. It has nice construction, great eye relief, and most importantly it is water (and thus fog) proof. Unfortunately however, it has collimation issues. It is not terrible, but still obvious. I've ordered the first pair by mail. Then came to exchange them. The few pairs I've tried (that were in stock) all had collimation issues to some degree.
Pros: Close Focus, Strong Construction, Waterproof, Works Well With Glasses
Excerpt: These binoculars are multi-purpose. I use them for sightseeing as well as looking at the stars. Although they are not as heavy as some binoculars, if you don't have a tripod, you need to steady them against something to prevent the image from bouncing around.
Summary: Well made with good optics, a little on the heavy side, this binocular is designed for astronomy though could be used for other purposes if needed, though not recommended, if you want bird watching binocular go for something smaller,however for the night sky it works very well. The lens caps could be a better fit however for its price its a very nice binocular.
Summary: Need some reasonably priced, large-ish aperture but still portable, high quality binocs? Then these might be for you! The optics are sharp to the edge of the field; fully multi-coated, so ghosting and other optical aberrations are minimal. They have enough aperture to yield bright night-time images of the sky, and can be used to track down some of the deep-sky objects that smaller apertures cannot.
