Hello ,

Does anyone know for sure if the 2 inch 42mm lanthanum
wide angle eyepiece has an apparent field of view of 72 deg. ? There
seems to be some questioning about this as the rest in the series are
65 deg. AFOV.


Also has anyone used this eyepiece with a refractor of
F 7 or F 8 focal ratio ? If so what was your impression of its
performance ?

Thanks in advance , Leonard
