Improving pointing accuracy
Every telescope has some kind of imperfections.
Nexus DSC supports two methods of improving
pointing accuracy that compensate for those
imperfections: sync objects and Mpoint. Mpoint is
described later in this manual.
Sync objects are used to improve the pointing
accuracy when a telescope is pointing in the
proximity of a synced object. Nexus DSC limits the
number of sync objects to 128. The size of the
area is limited to 10º radius. If there are more than
one sync objects in the area then corrections from
the closest sync objects are used.
Once the two star alignment is performed Nexus
DSC will enable an additional mode to allow
adding sync objects. Use
to activate it while
an object from one of the catalogues is selected:
To sync to the object (M79 in this example) and
make sure it is precisely in the centre of the field
of view and of any of offsets are are not exactly 0
then press the
key to add it to the sync
objects list. Once you press the
key you will
see that offsets became 0s:

Settings
Nexus DSC has a number of parameters that can
be adjusted. All of the adjustable parameters are
stored in non-volatile memory and will be used
every time you turn Nexus DSC on.
Please note that all settings can be reset back
to their default values by turning Nexus DSC
on while holding the
key. You will be
asked to confirm the reset to the factory
settings.
Telescope
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
:
Nexus DSC supports up to five different telescope
configurations. Each telescope configuration has
its own mount type, encoder steps, altitude
reference angle value. Having different telescope
configurations allows you to use Nexus DSC with
different telescopes without spending time on
setting all parameters.
Then you need to select the telescope:
and
keys are used to switch between
telescope configurations.
To select a telescope configuration without
changing any parameters just press the
key.
You can also rename

to your
telescope name. You just need to activate the
