•
Alt./Azimuth
Azimuth counted from north through east.
•
Mounting coordinates
Displays the angles for each of the mounting
axles. The horizontal coordinate is growing
from west towards east. The angles start at
zero when the mounting is powered up. Note
that the altitude coordinates are changed
when an alignment is performed.
•
Field rotation
– Turn rOTAtor on(off)
Displays the absolute field rotation angle and
the rotation speed. The absolute angle is
defined to be zero degrees when the object
passes the meridian. The right field shows the
field rotation speed in degrees/minute. This
information can be used to estimate how long
photographical exposures that can be made
without field rotation being visible in the single
exposures.
When field rotation is selected the optional
telescope rOTAtor is active. To turn off the
rOTAtor select another coordinate display.
See rOTAtor user manual for details.
Main Menu
Select this function to return to the main menu.
Goto Object menu
The Goto object menu is used to make a GOTO to an object or a position.
The menu contains the following functions:
Coordinates RA,DEC
Select this function to make a GOTO to a set of
celestial coordinates. The coordinates are entered
as described earlier concerning the hand pad. When
the coordinates has been entered the system checks
if the position is above the defined local horizon. If
that is the case the mounting will GOTO the position.
Otherwise a message is given that the object is
below the local horizon. The local horizon is setup
under location.
