Re: [APML] 35 mm Camera & Focuser

Serge,
    The Lumicon AOG probably won't work for you. As I understand it, the
flattener screws into the direct wide adapter, with your cameras' T-ring on
the other side. The direct wide adapter then threads onto the top of the
60mm focuser. The Lumicon OAG is 2" OD - it just doesn't fit anywhere. If
you could make it fit, it adds 7/8" height. When your R200 turns up, put
everything together and see how far out the camera is above the focuser. If
you have 7/8" or more, then you might be able to do something. I have a
picture of the 60mm Vixen OAG at
http://members.shaw.ca/jmirtle/files/vixenOAG.jpg . Not a great picture, but
it looks to be fairly thick.
    You don't need all that much of a guidescope for an 8" f4. I found an
old picture of Herm and his Vixen at
http://home.att.net/~hermperez1/ready_to_start.htm - looks like an 80mm f5
on top....
