I think in extreme cases where you have very highly contrasting objects in front of each other there is some fringing, but like the softening, the amount is really negligible and nothing to be worried about. Binoculars with larger objective lenses collect more light, which increases image resolution and brightness. Orion's telescope and astrophotography accessories will enhance your telescope enjoyment without breaking the bank.

A compact binocular prism system that allows the objective lenses to line up directly with the eyepieces and hence yields a more portable binocular. The distance, measured in millimeters, between the observer's eye and the eyepiece lens in which the entire field of view remains visible.Expand your viewing experience with accessories ranging from moon filters to power-boosting Barlow lenses to advanced computerized telescope mounts. It’s renewable, recyclable, durable, ages beautifully and it is an important part of our Scandinavian design heritage. We are happy to announce that we have reached this goal and today, more than 98% of the wood used for IKEA products is either FSC-certified or recycled. Unlike many telescopes, the APM Magnesium ED APO´s are portable and easy to take along on a trip, with or without a tripod.

Another quite important difference between these high end Celestron Echelon binoculars and the entry level Skymaster's is that the body on these has been fully sealed and they are described as being waterproof, whilst the Skymaster's are not. Celestron Echelon binoculars are tripod adaptable to provide extra comfort during long viewing sessions.

I have a number of these in most standard configurations, unfortunately as of yet, I do not have a giant benchmark binocular. The APM ED APO 10 x 50 binoculars is classed as offering IPX-7 protection, which means it will resist 30 min in up to 1m depth of water. However when it gets darker and your pupils dilate, bins with smaller exit pupils will seem less bright than equal quality ones with larger shafts of light exiting them.
