Wait for Altitude Action


This action will wait for the object entered to reach the specified altitude.  CCD Commander can automatically compute the altitude of the Sun, Moon, or any deep space object using its celestial coordinates.  For deep space objects, the coordinates are for the Epoch of the date the action is performed.  Only whole number values are allowed in each field.


When you select Sun or Moon in the Object Type box, the Object Coordinates and Object Name are disabled.  Only when Other is selected are these fields available.


The Get RA/Dec from TheSky button will pull the coordinates from the currently selected object in TheSky.  When you click this button CCD Commander will check to see what is selected in TheSky.  If there are multiple objects that could be selected, CCD Commander will display the following window to allow you to select your desired target from the list:


If your desired object is not show, click closer to the object in TheSky and push the Refresh button.


Alternately, you can enter an object name in the Object Name field.  When you click the Find Object in TheSky, CCD Commander will query the object's location from TheSky and automatically fill in the RA and Declination values for the object.  If the object is not found, CCD Commander will enter 0 in each of the RA and Declination fields.


Wait until object is at altitude specifies the altitude you want to wait until.  


Rising selects that CCD Commander should wait for the target to be higher than the specified altitude.  Note that the altitude you enter might never be reached by the object in question.  When this occurs, this action will complete when the object crosses the meridian.  If you want to simply wait until the object crosses the meridian, you can enter 90 degrees for the altitude.


Setting selects that CCD Commander should wait for the target to be lower than the specified altitude.


NOTE for GEMs:  CCD Commander does not monitor the position of the mount during the Wait action.  Therefore, it is best that your mount be in the parked position and not tracking if the Wait action will run for a significant period of time.  If your mount is tracking during the Wait action, you must ensure your mount is positioned such that it will not enter the safety limits during the Wait action.


The Compute Approximate Wait Time button will run CCD Commander's altitude calculation routines and report the approximate time your selected object will reach the altitude you have set.
