Checker Board pattern when image is stretched.

Hello Mabula,

I just started using APP and was able to do all steps including integration and saving.   However, when I transfer the final, saved image to Photoshop in either fits or tiff format I get an overwhelming artifact.  As I stretch the image, a checkboard or Herringbone pattern becomes evident that overwhelms the image.  I have tried some different actions including drizzle but it still remains.  I am guessing that it might have to do with the registration of my QHY163C images   ..  BGGR   one shot color.

Any guidance would be appreciated.

Thanks,

Leonard

Hi, I am getting the same colored checkered pattern after integrating my frames from an asi294 pro. I'm using the trial version of APP and have used pixinsight on this data with no issues. Is there something obvious that I am doing wrong.  Any help would be appreciated. 

Thx,

Alex

Thank you Vincent, I redid the calibration integration process and this time it turned out fine using the defaults.
