'Anyone familiar with the William Optics philosophy of high quality at a reasonable price will be glad to know that it extends to binoviewers. Conceived very much as an observing system, the unit comes in a presentation box with two wide-angle 1.25-inch eyepieces of 20mm focal length in addition to a 1.6x Barlow lens. The latter screws into the front of the binoviewer nosepiece, permitting you to use the unit with a wide range of scopes, from Newtonians and refractors to Schmidt- and Maksutov-Cassegrains. We were especially pleased to note that William Optics provides safety undercuts on the nosepiece and the eyepieces. This means that if the screws in your scope’s focuser or the unit’s eyepiece holders slacken off, your precious investment isn’t going to go crashing to the ground.'  BBC Sky at Night magazine

The Best of the Low-Cost Binoviewers
Wednesday, 24 August 2011  | 

I pretty much "live" inside my William Optics Binoviewers when observing the moon and planets with a large telescope. The extra detail revealed by the use of both eyes - as well as the added comfort - more than make up for the financial investment in them. Whilst it's true that the internals of most 1.25" binoviewers are more-or-less identical, the build quality of the William Optics model is a considerable step up from the alternatives. The included 1.6x Barlow lens is of excellent quality, and is in fact required with some Newtonian telescopes in order to achieve focus - although note that you might also need the optional 1.25" extension nosepiece in such cases as well. - Jeremy.
