Align by WCS


The Align by WCS command uses the world coordinate information stored in the image headers to align images to sub pixel precision. This command works with an image set. Alternatively, if no WCS calibration exists, or for general purposes, you can also align images using the Register Images command.

Note: This command may not give accurate subpixel alignment for images where the alignment involves higher order coefficients that are saved to the headers using non-standard keywords.

Procedure

You can also view all of the WCS related keyword data by using the WCS Keywords command.
