Cross Over Meridian
If your object of observation with the SXP mount is located on the east side of the meridian, the gravity of center of your telescope would be
on the west side of the R.A axis of the mount. As the mount turns at sidereal rate tracking the object which moves toward the culmination, the
optical tube approaches a place lower than the R.A axis of the mount. As a result, the optical tube may hit a leg of the tripod or the leg may
interfere with instruments installed on the optical tube. To avoid this, the SXP mount has a safety function which makes the optical tube turn
to the opposite position when the observing object comes to its culmination.
However, this may be troublesome if you intend to do astro-imaging of celestial objects in the
south side of the sky or photographing an object that is almost approaching to the
culmination during the exposure. The function of “Cross Over Meridian” allows you to
change a timing of the reverse motion of the optical tube. It is not possible to cancel the
revised motion itself.
The function of “Cross over Meridian” is a safety precaution to prevent the optical tube and equipped instruments from hitting the leg of the
tripod. Wrong settings could cause scratches or damage to the optical tube and instruments, and could result in injuries. When using this
function, be sure to check the configuration of each instrument installed.
In the “Mount Setting” menu, choose “Cross Over Meridian” with the or direction key and press the key (or the key) to call up
the dialog box.
In the “Cross Over Meridian” dialog box,
choose your desired option the or
