a)
Building the
Worm
Model
To
build the
worm
model, follow
the
following steps:
1)
Polar
Align the telescope (see Telescope Operation, pages 35-37).
2)
Position
a
star in the center of the fieH of view of the eyepiece. (Using
a
crosshair
eyepiece
helps.) Use as
much magnification as possible. The star should
be near the Celestial
Equator,
having a Declination as near
0o
as possible.
3)
Practice guiding on the star, keeping it exactly centered on the crosshairs by pushing the
ECC
Drive Corrector Buttons. Note: Make sure the slide switch
(#4, Fig.
20) is in
the 2X position.
4)
Press
CTL-F until Smart Drive gives 2 quick beeps, and
release
the two focus buttons. You
are
now in the Control
Focus Command
mode.
5)
Press the "W" button. This puts Smart Drive
into the
leach"
mode, and
Smafi Drive gives
3
long beeps.
At this point, the Smart Drive is waiting for a worm index pulse. This may take as long as eight
minutes.
During this time, keep the star centered on the crosshairs. Note: Smart Drive will start beeping 20
seconds
before it reaches the index pulse,
giving you time to get
ready.
When
the worm
index
pulse is
reached,
Smart Drive will give
3
long beeps. As you guide
on the star, Smart
Drive will give
1
quick
beep every 10 seconds
to let
you
know
it
is in the
train"
mode.
When the worm
model is complete,
Smart Drive will
give
1
long beep and automatically begin to compensate
for periodic error and other telescope function are resumed.
Note: During the training cycle, all other telescope functions are suspended.
lf any button is pushed
(other
than the 4 Drive Corrector
Buttons)
Smart Drive will
abort
the training session, erase what it
has
done,
and
give 4
long beeps signifying the end of the train session.
The worm model is
permanently remembered
by Smart Drive,
even when power
is
removed from the
telescope.
b) Erasing the Worm Model
lf
the
worm model
needs
to be
erased,
do the following:
1) Press CTL-F
2)
Press "E"
Smart Drive will
respond
with 4 long beeps and resume normaltelescope functions.
