2. Mount/GPS Status: display current
status of the mount. If the mount equipped
with an external GPS module, it also
indicates GPS status, when the mount is
turned on.
Land (Mount Status): the telescope is at
a standby position or observing a land
object;
Sola (Mount Status): the telescope is
tracking an object in Solar system at a
solar speed;
Luna (Mount Status): the telescope is
tracking the Moon at the lunar speed;
Cele (Mount Status): the telescope is
tracking a celestial object at a Sidereal
speed;
G-ON (GPS Status): GPS is connected
and trying to lock on the satellite;
G-OK (GPS Status): The connection
between GPS receiver and satellites
has been established. It will be replaced
by Mount Status after a few minutes.
3. R: Right Ascension of the telescope, or
R.A.
4. D: Declination of the telescope, or DEC.
5. A: Altitude of the telescope (zenith is
90º).
6. Z: Azimuth of the telescope (north is 0º,
east 90º, south 180º, and west 270º).
7. Local Date and Time: display local time
in a format of YY-MM-DD HH:MM:SS.
8. Slew speed: It has 5 speeds: 2X, 8X,
64X, 256X(1º/sec), MAX(4º/sec). Press
SPEED key to change it.
4. Getting Started
In order to experience the full GOTO
capability of GoToNova
®
technology, it is
very important to set up the mount correctly
before observation.
4.1. Level and Align the Mount
4.1.1. Level the Mount.
Leveling is critical for good GOTO and
tracking accuracy.
Level the mount by
observing the
bubble (shown) on
the base of the
mount by adjusting
the tripod legs.
The bubble should
be in the center of
the circle. It is also recommended to use
additional levelers (such as a torpedo
leveler) to assure precise leveling. Turn the
mount around by pressing or button to
make sure it is always leveled during
movement.
4.1.2. Initial Positions
Each time the mount is turned on, the
default position is Park Position, i.e.,its
altitude is 90º0.0’ and azimuth is 180º0.0’,
which means the “SOUTH” mark is pointing
to south and the telescope is pointing
straight up at the zenith. To set the Park
Position, you can do one of the following:
1. Align the mount to south by turning the
mount so that the South mark facing south.
An additional compass is needed. Unlock
the altitude lock (#4) and rotate the
telescope to point straight up at the Zenith.
A torpedo level may help. Make sure the
mount is leveled. Then turn the mount
power on.
