Of course, the 7x18 and 8x22 could have the same eyepiece.
The lower power would give the 7x18 a slight improvement in field edge quality.
Carson (in the past 8 yrs) has done really well with QC from China,
and China has been putting out some interesting eyepieces.
I salvaged some really fun 8mm RKE (Konig with a top curve) EPs from a busted pair of
Celestron 12x25s. The prisms and objective brought the view down a bit,
but the EPs are great in a telescope.
