William Optics Binoviewer Package

[dumdidum]

I was looking at purchasing this through the online store for viewing through my 10" GSO dob. The rep advised me that I would probably need the optional 2x ocs. Just wondering if anyone has had any experience with this combination of equipment and could confirm this? I have also found an "extender nosepiece" attachment which I'm guessing I may also have to buy...

Thanks

I beleive that all reflectors (and many refractors) will need an OCS (Optical Corrector System) regardless of bino type to come to focus.

I've got the Denk "Big Easy" and it came with an OCS...different combinations of the OCS configuration allows different magnifications. It all works a treat.

I can't speak to the quality of the William's sets...I am pleased with my Denks.
