In my 40+ years of amateur astronomy, these are the worst binoculars I have ever looked through. Even my old $30 Bushnell 10X50's are much better optically. These Oberwerks are well made, fully multi-coated, well collimated and have a nice smooth focus knob. But the optics are rife with chromatic abberation and coma, and the right side does not focus quite as sharply as the left. The inside of the objective lenses have some dust and debris which suggests poor cleanroom practices and a lax quality assurance program. When viewing bright objects like the Moon or Jupiter, the CA/coma is terrible, extending far enough from Jupiter to blot out its closest moon under a blob of light. On bright or medium stars, coma causes them to have a 'tail' of light. These anomalies are very apparent in the of the field of view and only get worse as you move toward the edge of the field. The binocular does work well for long range terrestrial viewing; and diffuse objects such as nebula, star clusters and the brighter galaxies look fairly good (thus the 2 star rating instead of 1), but they would look much better through decent optics. These are large and heavy, as are all binoculars of this class, and cannot be handheld; I had mounted mine on Orion's Paragon Plus parallelogram binocular mount/tripod (excellent, see my review). So, if you are serious enough about astronomy to want large binoculars, do some research for higher quality optics that won't turn you off to binocular astronomy. Some BETTER optics cost LESS than this monstrosity. Celestron, Meade and Orion are some of the better known brands that come to mind, but at this price point most will have Chinese optics, although Orion has some nice choices with the better Japanese optics at around this price or even less. If you have a pile of cash to spend, go with Fujinon, the gold standard by which all others are judged. These Oberwerks are now sitting in a closet, gathering dust, and I am lusting over Fujinon's 16X70, flat field binocular. I'm sure I will be ordering it soon. I will never buy Oberwerk again.
