Homing - Software Bisque Paramount MX User Manual

TPoint can be employed to take care of the atmospheric refraction details for you.
•
TPoint's Super Model feature and Polar Alignment Report automatically determines the position
of the refracted pole and give recommendations on how to proceed, including how much to
rotate the altitude and azimuth knobs when adjustment is necessary.
•
It accounts for and applies refraction when acquiring telescope calibration data as well as
corrects the telescope's position when the mount is slewed.
•
TPoint's ProTrack feature can be used to apply tracking corrections to the mount based on the
point calibration data.

Homing

Finding the home position, or homing the Paramount MX is an automated initialization process that
slews both axes to the mechanically fixed or absolute home position. Homing must be performed every
time the Paramount MX is turned on so that the control system can establish the mount's position and
restore the synchronization information.
In other words, after the mount is homed and the previous session's synchronization information is
applied by TheSkyX Professional Edition, the telescope will know its orientation and have the same
pointing accuracy as the previous imaging session.
When a Find Home command is issued from the hand controller (page 61) or TheSkyX Professional
Edition (page 74), the mount slews to the home position and zeros the control system's "position
registers". When the mount is subsequently synchronized on a star, the computed hour angle and
declination of the home indices are stored in the internal flash of the Paramount MX's control system.
•
The home position is located at hour angle 2 and 0 degrees declination. The
absolute home position is a fixed, mechanical orientation and cannot be
changed; it is defined by the physical position of the gears relative to fixed
internal homing sensors.
•
If the mount is not physically pointing to approximately hour angle 2 and 0
degrees declination after finding home, then either the Versa-Plate is
mounted incorrectly, or the mount's polar axis is not oriented north-south.
•
If, after homing is complete, the coordinates of the telescope cross hairs
displayed by TheSkyX Professional Edition indicate that the mount is
pointing anywhere other than the home position, then either TheSkyX
Professional Edition's location, date, time or time zone is not correct, or the
mount has been synchronized incorrectly. See "Synchronization" on page
19 for more information.
The Paramount MX cannot slew or track until the mount is
successfully homed.
