For the two Baader eyepieces which just happen to hail from the same manufacturer (specifically the Genuine Ortho's and the Eudiascopics) Baader reports the RFOV, but sadly they quite confusingly report it under the term AFOV.

As a result, where U/O reports the AFOV of their HD Ortho's as 43 degrees, Baader reports this as 40 degrees for their essentially identical Genuine Ortho's. Likewise where Orion reports the AFOV for their Ultrascopics as 52 degrees, Baader reports the AFOV for their essentially identical Eudiascopic's as 45 degrees or so.
