Next Steps

Automatic Weighted Batch Pre-processing for Comets 


  1. Basic PixInsight Function
  2. Image Preparation Options
    1. Image Preparation  for Stars and Deep Space Objects (DSOs)
    2. Processing Mosaic Images
    3. Processing Comet Images
    4. Adding Astrometric Data


Some later steps may require Astrometric data (OBJCTRA and OBJCTDEC) to be included in the FIT, FITS or XFIT header of the integrated file. To some unknown reason this information is missing since a while after performing automatic batch pre-processing.


In order to reintegrate the astrometric data into the files, a plate solving (Image solver) should be carried out. Depending on the brightness of the image background, a background improvement may have to be carried out first so that the image solver does not fail.
