a 2X or 3X Barlow lens. Then follow this procedure:
1. Place the Illuminated Reticle Eyepiece (or
Eyepiece/Barlow combination) into the eyepiece-
holder of the telescope.
2. point the telescope with the motor drive running,
at a moderately bright star near where the merid-
ian (the North-South line passing through your
local zenith) and the celestial equator inter-
sect. For best results the star should be lo-
cated within! 30 minutes in R.A. of the meridian
and within! 50 of the celestial equator.
3. Note the extent of the star's drift in Declina-
tion (disregard drift in Right Ascension):
a) If the star drifts South, the telescope's
polar axis is pointing too far East.
b) If the star drifts North, the telescope's
polar axis is pointing too far
~.
4. Move the wedge in azimuth (horizontal) to effect
the appropriate change in polar alignment. Re-
position the telescope's East-West polar axis
orientation until there is no further North-
South drift by the star. Track the star for
a period of time to be certain that its Decli-
nation drift has ceased.

6. Again note the extent of the star's drift in
Declination:
a) If the star drifts South, the telescope's
polar axis is pointing too low. .
b) If the star drifts North, the telescope~s
polar axis is pointing too high.
7. Use the latitude angle fine-adjust control on the
wedge to effect the appropriate change in latitude
angle, based on your observations above. Again
track the star for a period of time to be certain
that Declination drift has ceased.
