'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

WO binoviewer
Friday, 27 July 2018  | 

The view of the moon through the WO binoviewer (attached to cpc 9.25) is breathtaking,
they are quite heavy so if using with a star diagonal make sure every thing is tightened down.
Highly recommended.

new favourite kit

Solidly built and reassuringly heavy. Adjusting eyepiece focus to account for individual differences is straightforward, but I found it too easy to alter the setting, once made.
It took lots of fiddling with the focusser extension tubes on my 4-inch refractor to get the binoviewer to focus.
Without the diagonal, the image was inverted, so the solution was to eliminate the extension tubes entirely and just use the diagonal, with the Barlow.
On my 9.25 SCT there were no such problems, with or without the Barlow.
I'm glad I chose the WO binoviewer with the WO lenses. They are a good match for the viewer, and give an excellent MoonWalking experience.
Performance is impressive: I could make out Saturn's Cassini division (in quite poor seeing conditions) and could split the Double Double into four, neither of which I could do in cyclops mode.

Firstly as always excellent service from Flo. I bought these for my nexstar 6se. Having bought a WO star angle I knew these would be good and I'm not disappointed. The foam filled box they came in is great for storing them safely. The supplied eyepieces and barlow are very good quality and perfectly matched to the bino's. No free play evident at all. The binoviewers are light and well made and the brass maring rings hold everything solid. The diopters are slightly stiff to adjust but this ensures they stay put. I have had no problems with merging the images and everything is crisp and clear. There was some slight dimming when viewing the Orion Nebula but this was more than compensated for in the extra detail I could see. I found viewing through two eyes very relaxing.
Overall for my budget these were an excellent upgrade for the 6se.

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.
