RE: [APML] Search for flexure and mirror movement info
1) If
you have spring loaded bolts for the primary you need to get rid of the
springs
and
drill and tap for three additional bolts so that it is a push/pull
arrangement.
2)
Most visual newtonians have entirely too thin spider vanes. You may need
to
replace them with something thicker.
3) The
secondary is often just three bolts with no loading. You'll need to
either
add a
push pull arrangement for this or add a central pivot point which you
will
use
all of the bolts to pull the secondary against.
4) You
may need to counterbalance the secondary. But with a thick enough
spider
you
shouldn't have to.

Hello All,
I'm trying to get a newtonian to work with a guide scope. I must
eliminate all flexure or mirror movement as much as possible. I have
heard that some people have done this and are successfully using newtonians
with a guide scope. However, I have had trouble finding how this was
accomplished on the internet.
Does anyone know of a good comprehensive source of information of how to
track down and get rid of flexure and mirror movement troubles, so that I can
use a guide scope with good results?
Much thanks,
Adam
