Re: [APML] 35 mm Camera & Focuser

Thanks Serge,
    Not much has really changed then. Herm Perez can probably confirm
this.... As I understand it, there isn't enough back-focus on the R200 to
install an OAG. In other words, if you install one, it won't rack in far
enough for the camera to focus.  :- (

John,

Here is an extract of the email I received today from Bill Copeland, Sales
Manager of Vixen North America, regarding the changes they made to the Vixen
R200SS with respect to the focuser and off axis guider:
-------------------------
... Vixen responded saying that the distance to the focal plane on the
R200SS is
the same as the old design (72.5mm standard and 78.0mm with the coma
corrector installed.  On the focuser, they have changed the rack & pinion &
knobs as well as the eyepiece holder on the newer model.  They also
responded saying their off axis guider will not work with the R200SS so I'm
not sure about the Lumicon model?...
