The best thing about these binoculars the great price, so great that I decided to take a chance and get a pair...One thing I really DO like is the objective covers, they fit well, and have little "ears" that allow them to be removed easily. The eyepiece cover, on the other hand, is very loose (not usable).Also, while it is not the BEST solution, I was happy that the "Super Giants" came with a case at all; for the price, you might not expect to get any "extras."One "extra" they should have left out, however, was the lens cleaning cloth, I would avoid using this cloth, as it leaves a lot of lint, and it's also not particularly soft.Overall they have the makings of a decent instrument, but they need some help...The main problem I had was that I could not get the diopter to adjust so that both of my eyes had good focus at the same time (without my glasses on)... I bought these binoculars for astronomical observation. When you are viewing pinpoints of light, accurate focus is CRITICAL!Another Issue I had was that the center focus mechanism was somewhat flimsy (although better than some cheap Bushnell's I have), leading to an unacceptable shift in focus if you so much as touch the eyepieces with your face or glasses.Furthermore, although this website claims that these "Super Giants" are fully Multi-Coated, I can say for certain that they are not... The coatings on the objective and eyepiece lenses have the tell-tale faint blue reflection indicating a single layer coating. Moreover, internal reflections while looking at bright objects at night are nothing short of SIGNIFICANT. This suggests that the prisms may be completely uncoated.Because of the shortcomings of this pair of binoculars, I would NOT recommend they be used for astronomy, as it seem this is simply too demanding of an application.The price redeems them somewhat, and for watching wildlife or long range observation of other terrestrial targets, they will do the trick... The 80mm objectives will give better low-light performance than other binoculars, and for the money, you just can't touch anything else this big. Finally, keep in mind that at 20x magnification, they will be almost useless to you unless you mount them on a tripodIn contrast to the binoculars themselves, [...]
