Set Mount Position
The Set Mount Position menu can be used to maintain your alignment in cases where you wish to disengaged the clutches or
similar situation. For instance, you might use this feature if you needed to rebalance the mount after having completed an
alignment. To set the mount position simply slew to a bright star in the named star list then select Set Mount Position. The
hand control will sync on the star by asking you to center the star in the eyepiece and pressing the Align button. Once synced
on the star, you are free to manually move the mount in both axes in order to rebalance. When you are ready to slew the
telescope to your next object, just remember to manually return the tube to the same bright star and carefully center it in the
eyepiece. Using this tool will invalidate the PEC index.
Turn On/Off GPS
-
If using your telescope
with the optional CN-16 GPS accessory (see
Optional Accessories section of the manual),
you will need to turn the GPS on the first time
you use the accessory. If you want to use the
telescope's database to find the coordinates of a
celestial object for a future or past dates you
would need to turn the GPS off in order to
manually enter a time other than the present.
Turn On/Off RTC
-
Allows you to turn off
the telescopes internal real time clock. When
aligning, the telescope still receives time
information from the RTC. If you want to use
the hand control database to find the
coordinates of a celestial object for a future or
past dates you would need to turn the RTC off
in order to manually enter a time other than the
present.
Periodic Error Correction (PEC) - PEC is
designed to improve photographic quality by
reducing the amplitude of the worm gear errors
and improving the tracking accuracy of the
drive. This feature is for advanced
astrophotography and is used when your
telescope is accurately polar aligned. For more
information on using PEC, see the section on
“Astrophotography”.
