Search didn't turn out much.
Does anyone have experience with it?
Please share your experience.
I am interested in how it stands up against Nagler 31 and Leitz 30 if it is possible.

Yes, that's one. I placed an order. I'll find it myself.
I'll report back here when I get a chance to compare with 30mm-ish eyepieces. No, I don't have neither Nagler 31 nor Leitz 30 to compare but I can do with UWAN 28, Tak LE 30, Paragon 30, Hyperion 31, RKE 32, TV PL 32.

Wow, that looks interesting. Looking forward to hearing how it performs.
It is here. It has unique look, as APM America web site describes research equipment look
From left to right, UWAN 28 (957 grams), BW/Zeiss 30 (771 grams), Ethos 17 (721 grams), and TMB Supermonocentric 7 (56 grams) for size comparison.
It looks like BW/Zeiss 30 coating is inferior to others.
I see more reflection from eye lens.
I haven't done first night light yet except terrestrial viewing. BW/Zeiss 30 is easy to look through (good eye relief), noticeable field curvature with f/7.5 refractor.
My intention is to use this with Vixen VMC 260L f/11.5. I hope it performs well under night sky.

Is there any functionality to the square part of the EP, or does it simply hold the 2 "halves" of it together?
No, I don't find any good use of the square 2" adapter. It must be coming from original research equipment requirement or something.

I'll loan you my Nagler and Leitz for the shoot out. PM me when you want to get together or send me an e-mail.
