John I was referring to the 30mm gso superview.
I am familiar with the gso 2" kelner types and I owned the 26mm having originally paid $140 for it
I agree that the kelner series were bad for aberrations, diabolical even at f5. But, I found the contrast and transmission of the kelner far superior to the gso superview. All of the SV series I have viewed through remind me of viewing through dirty glass, they just dont seem clear.
FWIW, I tried the 20mm sv in my ed80 refractor (f7.5) and aberrations were still far from acceptable to me.
