Tutorial



GraXpert must be used 

  • after cropping 
  • and before any other image processing. 


GraXpert will fail on non-cropped images (within the left over black frames of the image integration) and also on already post-processed images.


Please note that the PixInsight script integration of GraXpert is limited to the AI mode without the possibility to change any parameters. If you want to use the full power of GraXpert, use the standalone version of GraXpert instead.
