How does a person with just two eyes end up with 3 binoviewers (and a 4th on the way)?!? Best not to ask. Suffice it to say, I am sold on the advantages of two-eye observing, and selling the extra binoviewers seems wiser than installing extra eyes Posted Image .
All of the following are ATM-converted microscope heads which provide very nice views, and are collimated well enough that my eyes can merge the images. Prices include Priority shipping to the US. PayPal or postal money orders would work well for payment.

Nikon Binoviewer w/48mm filter threads & 2” nosepiece + eyepieces $100 SOLD to Steve P.
This has 48mm filter thread for attachment to a 2” focuser using the included 2” eyepiece extension tube or a (not included) 2” Barlow lens cell. I'm including two pair of microscope eyepieces, both 10x = 25mm fl and ~40° AFOV). One pair are Nikon Bi HKW, the other are no-name CPl W10x.

Nikon Binoviewer/Lumicon 2” Diagonal Combo + eyepieces $115 SOLD to Chris
This was modified by someone else to be as compact as possible for a refractor/SCT/Mak/Cass that can take 2” accessories. My refractor (Vixen ED100sf) was able to focus these at infinity, sans Barlow. For full disclosure, the mirror's surface has some faint (coating only?) scratches, which do not harm the view, IMO. If you insist on a pristine mirror surface, I can also include a new old stock Meade 1.83” secondary mirror for you to swap in. This comes with two pair of Nikon focusing microscope eyepieces; 10x (25mm fl and 40° AFOV) and 15x (16.7mm fl and 48° AFOV).
