Heres some full res. crops, with Levels adjusted the same for both, the crop taken from near centre of both images, and converted tp CFA colour with IRIS as I would with an astrophoto

PS, with IRIS, the remaining "Deviant Hot Pixels can be removed easily, and other software can do the same. Its mentioned here

FIND DEVIANT PIXELS INTO THE THERMAL MAP
Some pixels are affected by a high value thermal parasitic signal. The rate signal of "hot pixel" can be non-linear. A special procedure permit to erase bad effect of this pixels in the final result.
This cosmetic correction apply the local median to a set of pixels on the image of a CFA image, around each hot pixels (a separate procedure is used for red, green and bleue pixels). The coordinate of the hot pixels are in an ASCII file. This file, known as cosmetic file, is then used by Iris to correct certain systematic defects during the preprocessing of the deep-sky images. The extension of the cosmetic file is .LST (list file).
For construct the cosmetic file use the in-line FIND_HOT command on the dark frame master image. So, the produced file will contain coordinates of the pixels affected by an abnormally high dark current, up to a given threshold.
First, reload the dark frame:
>LOAD DARK
then:
>FIND_HOT COSME 150
The first argument of FIND_HOT is the cosmetic file name (here the file COSME.LST is created onto the working directory). The second argument is the threshold. The command return the number of hot-pixels found up to 150 intensity value in the example. Try successive values for this threshold and examine the result in the final image. The typical useful number of hot pixels listed is between 0 and 500.
