I had a strange experience with PixInsight 1.7 when I was processing an image. When I was using HDR tool, it would remove or strip out lots of data from my image. Also, after using HDR, I extracted Luminance from color image for Luminance mask, the Luminance background was horribly noisy and grey/white probably because of bad HDR processing.
So I ran "Reset PixInsight settings" and everything is back to normal. Is this a known issue?
Thanks,
Peter
