I like the number Greg E. mentioned, because after sanding two
adjacent sides
of a pair of Horizon loupes until I could "see" through the
black plastic, that is
the separation I arrived at, and that will have to do for the
time being. One J.
Bercovitz drawing I downloaded specs 65 mm. other sources I
looked at spec'ed
a few mm less. On my "ultimate" viewer (if I ever build it) I
would like adjustable
interoccular.
And now, more comments on Bill Glickmans travails: I assume
the cameras are
"shooting" parallel in these discussions? Has convergence or
"toe-in" reared its
head yet?
Regards,
John Billingham
