select the parameter that needs to be adjusted.
and
keys are used to change the value.
Setting the time and date is only required if time
synchronisation with GPS is disabled. However
the time zone and date needs to be set for Nexus
DSC to show the local time correctly.
It usually takes 30 to 60 seconds for the GPS
receiver to get a fix on the location (under
open sky conditions). Nexus DSC will update
the internal real time clock with the time
received by the GPS receiver at this time. The
GPS receiver will automatically be switched
into a power saving mode after it acquired the
location to conserve the battery power.
Connecting to your telescope
Nexus DSC requires only encoders connected to
operate. Please plug the encoder cable into
Encoders
port on Nexus DSC.
For operating Nexus DSC with a ServoCAT or
SiTech controller the serial port needs to be
connected to a serial port on ServoCAT or SiTech
controller.
To make sure that encoders are functioning
correctly Nexus DSC has a test mode to test the
encoders. Selecting
Test
from the main menu
activates it:
Then select
Encoders
:
will show the current angles and encoder steps:
In order for Nexus DSC to function correctly it is
required to adjust the encoder steps to make sure
that:
•
the RA/AZ current position in degrees is
increasing when rotating the telescope
clockwise around RA/AZ axis
•
the Dec/Alt current position in degrees is
increasing when moving the telescope up in
declination/altitude
If either of those values is decreasing then set the
encoder steps’ sign for that axis to a negative sign
in the Telescope Settings:
Telescope Settings
Nexus DSC needs the mount type and encoder
steps to be set correctly before it can be used to
locate celestial object precisely.
The mount type and encoder steps are set in the
Telescope Settings that can be accessed by
selecting ‘Setting’ from the main menu:
then by selecting ‘Telescope’:
Then you need to select the telescope:
Nexus DSC allows to have up to five different
telescope configurations.
and
keys are
used to switch between telescope configurations.
You can also rename
TELESCOPE 1
to your
telescope’s name. You just need to activate the
Rename
button by using
and then press the
key. A text cursor now appears under the
name:
