Zeroing Telescope Coordinates

Friday, April 1, 2016 9:03 AM

Problem(s) Encountered:

How does one zero the coords on a target?  The zero dialog does not work on the TCS and the ''zero'' command does not appaar to update the coords.  I was forced to always do a 2.5 arcmin offset after slewing to a position.


Solutions:

To zero coordinates: zero ra=ra dec=dec equinox=equinox

So for instance, zero ra=23:14:35 dec=-08:15:23 equinox=2000


Alternatively, one can enter the coordinates that you know you are pointing at in the JSkyCalc main window, and update the pointing with the appropriate button in the JSkyCalc telescope control window.  A confirmation dialog box appears to be sure you didn''t hit the button by mistake.

The important thing is to be sure you''ve reset to the correct coordinates before you go off your target.
