Skip Ahead when Object reaches Altitude Action


Similar to the Skip Ahead at Time Action, this action will cause CCD Commander to skip ahead to the point that this action is in your list when your specified target reaches the altitude you specify.


This action performs identically to the Skip Ahead at Time Action.  When you start running the action list, CCD Commander performs the calculations necessary to determine at what time the specified object will reach the desired altitude (either rising or setting).  Then when the time is reached, CCD Commander will execute the skip.


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.


Skip when object is at altitude specifies the altitude you want to skip at.  


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 CCD Commander will skip ahead when the object crosses the meridian.  If you want to simply skip when the object crosses the meridian, you can enter 90 degrees for the altitude.


Setting selects that CCD Commander should skip when the target is lower than the specified altitude.  If the target can never go above the specified altitude, the skip will activate as soon as the target crosses the meridian.


The Compute Approximate Skip 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.


Enabling the Soft Skip option will cause CCD Commander to not skip at exactly the time requested if an image is in process.  CCD Commander will wait for the image to complete prior to executing the skip.
