What does "calibrate GoTo" mean?
      #5802404 - 04/16/13 11:48 AM

hi folks,

in the "utilities" section of my handcontroller (european/german version) i find a no where else mentioned task "calibrate GoTo". i can not find anything about this procedure in the manual.
when i press the enter button the scope makes a short removement towards the actual tube position and continues tracking then. i am wondering about the purpose.
can you explain please?

thank you!

From Celestron-

Calibrate GoTo – Goto Calibration is a useful tool when attaching heavy visual or photographic accessories to the telescope. Goto
Calibration calculates the amount of distance and time it takes for the mount to complete its final slow goto when slewing to an object.
Changing the balance of the telescope can prolong the time it takes to complete the final slew. Goto Calibration takes into account any slight imbalances and changes the final goto distance to compensate.


You do this after you set any anti-backlash compensation and after performing a good alignment. You do not need to to do it again unless you change the scope's weight and balance.

I do this with both the CPC mount and the Nexstar SE mount and it does seem to slightly improve goto accuracy.

Glück und klarem Himmel.
