AFOV and eye relief.
85¡ã vs. 100¡ã AFOV and the new was have 19 mm eye relief.? I don't recall what the Ethos have, but you can easily look that up or know it already from using them.
Tye 7s are nore Nagler plus than they are Ethos. You'll recall the Space Walk ads for Naglers and their 82¡ã AFOV, right?
Just a little more filling a niche where they were no type IV or VI.
The pics show them looking like the Apollo 11 Commerative Eyepiece too.? I suppose that's part of it.
I doubt you'll see any in the scratch and dent sale at NEAF this year is my guess.?

What would the distinguishing characteristic differences be vs my Ethos 21mm and 13mm that are pairing well in my f/8 ACF? (And in the 82ED as it turns out.)
