Precise GoTo

Introduced with NexStar hand control version 4 (first included with the CPC) and available in all newer versions, Precise GoTo provides pinpoint accuracy to place an object right in the center of the field of view.  This is most useful when imaging objects that are visually undetectable and so you must rely on the scope to place the target right in the center of your camera.

Procedure:

  • Press the Menu button then use the UP/DOWN buttons (6/9 on the number pad)  to scroll to Precise Goto and press ENTER.  Generally it is quickest to scroll UP.
  • Use the UP/DOWN buttons to select whether the object you are interested in is in the hand control's database (catalogs) or if you will need to enter the RA and Dec of the object.  Press ENTER to proceed.
  • If you selected RA/Dec, simply enter the coordinates.  If you selected database, use the UP/DOWN buttons to scroll to the correct catalog and press ENTER.  Use the catalogs as you do for a regular GoTo.
  • After selecting your target object and pressing ENTER, the hand control will present a list of stars near your target.  Select any of these stars and press ENTER.  You are presented with a list of possible stars since one of them might be obscured by a tree, etc.
  • After pressing ENTER, the scope will automatically slew to the star you selected.  Center the star in the eyepiece using the same arrow keys as used when you initially align the scope.  Press ENTER and the scope will now slew to your actual target object, placing it precisely in the center of the field of view.
