If you want to talk to Geoff - try a direct e-mail - usually works best.

Yes,just checked my Vixen guide book, F5.7 is correct.

To the Op,I had the gentleman selling this refractor visit our country property on Saturday,just gone,He bought this instrument along and had it on his EQ 6.I did some visual viewing through it-its a very good optical tube,excellent optics-not a mark on it,I'd buy it if I could afford it.
