I have a problem when stacking M13 with PI. Image calibration, debayering and registration just goes fine without errors, but final stacking (using ImageIntegration process) gives really bad results. I have two example pictures here:
Example of one calibrated, debayered and registered file: M13_esim_c_d_r_small.jpg
Final stacked image (from 39 individual images of M13): M13_master_small.jpg
The results is really bad and fuzzy. Does someone know what might be problem? I don’t have any problems when stacking nebula images like M27, but I have these problems with star clusters and galaxies.
Many thanks for your help in advance!
