>I had completely forgotten about the feather touch. I played with one at
RTMC a while back and it seemed like a nice unit. I will have to see how
hard it would be to stick a robo-focus on it. What sorts of mods did you
find were necessary on the focuser?......

One seems pretty dumb but such is life.  The two screws that hold in the
eyepiece, camera etc are 180 degrees apart which makes a great rocker.  I
just drilled and tapped another hole 120 degs from one of them.  I told him
about this and it just never occurred to him and he may have changed it by
now.

The other thing I did was to make an indexed knob with a pointer so I could
tell where I was going and coming from when camera focussing.  The other
escapes me now and I think I decided to live with it and aparently haven't
suffered much.

Other than that it really is nice and does what it claims.  Most
importantly, zero shift.  All you have to do with a JMI "Zero
Shift" is spend a night trying to image a planet at high magnifaction
to appreciate what bunk the claim is... it is rarely even on the chip after
a focus tweek. With the feather touch, zero is in the eye of the beholder
but it does stay very close to where it was.
