Does anyone know the optical quality (1/4 wave, 1/8 wave etc) of the Siebert Black knight 22mm ca Binoviewers. Also has anyone compared them to the Denk standards or Eathwins?
I know that the ca is smaller on the Siebert but other than that is the optical quality in the same league?
The scope it will be used in is an EON 120 Ed.
