I’m having issues with calibration frames in my final image of Pleiades. There’s a fixed pattern (you can see it on the right) that should have been removed with my bias, darks, and flats. This Is from an unmodded Canon 5D IV. I exported the raws (CR2) from Lightroom into a folder, and open them on DSS from there (Lights, darks, bias, flats). I’m processing in Photoshop. This is the same workflow I’ve used before with no issues. Also, the final image from stacking is coming out 115 MB 16 bit TIFF, where in the past it was much higher 347 MB and higher bit depth. I would convert to 16 bit in Photoshop, but now it starts at 16. I’m not sure these two issues are related, but sharing these issues in case related. I have less than an hour of data, which I know affects the image quality.
Any ideas what might be causing this?
