Here is the same data with an uncorrected flat.

The really faint data is far better.

Do I read the title of the second file correctly and guess it is a HDR processed file or is it a true corrected or uncorrected raw image with just a possible linear or curved stretch?

With both images could you also give some idea of the actual calibration used. eg. Flats, bias and darks or Flats, flat darks, darks etc. It will make understanding the diference a little easier.

Thanks
