2 eyes are better than 1 - right?
This is certainly the case with this quality piece from Williams
It is well made and the bulk and weight of a top end CSC body. This means that you have to be careful to make sure that it is well tightened and secured to your telescope.
I have poured mine wirth a 6 inch SC and the match is perfect.
The image is clear and crisp and make viewing more comfortable and enjoyable

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.

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

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.
