Since most of us must set up our instruments in the dark, in the cold or while battling mosquitoes, a bit of preplanning
and organization is important. There are a few simple things that can be accomplished in the comfort of your home
before heading outside.
GROSS LATITUDE ADJUSTMENT
astronomers typically observe within one latitude range, this adjustment is made just once, if at all. Prior to
shipment, we preset the mount to your latitude range for your convenience. If you travel to another observing
location, determine the latitude of your observing site and make the appropriate adjustment.
The four positions for the altitude adjustments have the following ranges:
55 degrees to 68 degrees latitude – top position
37 degrees to 59 degrees latitude – third position
28 degrees to 50 degrees latitude – second position
20 degrees to 37 degrees latitude – bottom position
How to change the position of the altitude adjuster bar
1. Use only the R.A. axis. DO NOT attempt to
make these adjustments with the declination
axis in place and certainly not with an
instrument fully mounted.
2. Loosen both altitude-locking knobs about one
turn.
3. Locate the side of the polar axis that does not
have the motor/gear housing box. Loosen
(about one turn) the polar axis pivot screw and
altitude adjuster bar fixing screw on this side
only. With your hand, push the polar axis
upwards so that the altitude locking knobs are
positioned at the top of the altitude slot (this is
the maximum altitude position). Some
resistance will be felt with this operation as you
are pushing against the weight of the polar
housing and the resistance of the remaining
polar axis pivot screw (which has not been
loosened).
4. Before attempting to move the altitude adjuster
bar, you must tighten the altitude-locking knob
on the motor/gear housing side. This will
prevent any downward movement of the polar
axis during positioning of the altitude adjuster
bar.
5. While supporting the altitude adjuster bar,
remove the two screws that support it on either
side, but keep the two ends of the bar in
contact with the side of the mount. Don't
remove it completely. This tip is for your
convenience.
