Enter x y pixel coordinates of the centroid of object of unknown RA Dec

To determine the RA, Dec sky coordinates of your object (an asteroid, for example), you need to specify it's x,y pixel coordinates in your image. You need to determine accurate pixel coordinates (to a fraction of a pixel) of the "center of light" (the centroid) of the object's image. To determine these centroid coordinates you can use SIP's Instrumental Magnitude and Centroid selection under the the Analyze menu item.

The x, y entry format is xx.xxx... yy.yyy... (e.g., 327.67 123.45). Once, again the only rule is that these two values must be separated from each other by one or more spaces.
