Hi Matt, I processed the TIFF you sent in Astra Image 2. Your original at left and the reprocessed at right below. The original has some faint halo - not sure what's caused that.
Processing details were as follows:
Converted and cropped to BMP and brought into Astra Image 2.
Split colour frames and ran LR deconvolution on each - 4 iterations at 1.8 curve
Recombined in Astra Image and saved as BMP file.
Played with colour and luminance in Made Safe Photo Paint using curves and brightness/constrast.
Saved as jpeg.
What do you reckon?
