Description
in control system's position occurs at this rate.
The general rule of thumb is that the fewer number of corrections to the
mount's position that are made during autoguided exposures the better
the resulting star profile. So, a guide rate of fifty-percent of sidereal rate
(the default setting) is the optimal value to achieve this goal.
The percentage of the mount's maximum slew rate that is used to slew
the mount.
The sidereal tracking rate in control system tracking units.
The Bisque TCS will not drive the motors beyond this minimum limit
(decelerating stop).
The Bisque TCS will not drive the motors beyond this maximum limit
(decelerating stop).
The calibrated center position of the joystick.
The relative home sensor position is computed using both the mount's
fixed homing sensor location and the equatorial coordinates supplied to
TheSkyX Professional Edition when the mount was synchronized on a star.
For a perfect mount that has no optical or mechanical misalignments,
mechanical flexures or polar alignment errors, the relative home position
would identically match the absolute mechanical home position. This is
never the case. Misalignments in the mount's mechanical axis and the
telescope's optical axis, for example, always introduce telescope pointing
errors so there will always be a difference between the relative and
absolute home position after synchronization.
When the mount is synchronized to a known star, the "relative location of
the home position" changes based on the pointing error introduced by
the mechanical and optical misalignments.
When the relative and absolute home sensor positions are equal, it
means the mount has not yet been synchronized on a star.
After synchronizing the mount, choose the Get All Bisque TCS
Parameters command from the Commands pop-up menu on the
Parameters tab (see page 84) to retrieve the control system's current
