OK finally I can post a progress report. The first of the two = secondaries
required for my DK bino-scope is, I think, finished. Under = the fringe
test I have two bearly disernable rings and when the wedge is = applied the
lines (about 40-50 of them) are very nearly straight. I mean = there is
about 1.5 freinges of deviation over the width of the blank.

Is this good enough? I will over the nest week or so build a lashup to = do
a laser dot star test of the system, so I guess this will really tell =
all.

Well comments etc welcome.

Clear skies, Thomas.
