I hope this looks ok, it's the best I can do:
It's a Levels layer:
On the RGB channel, move the middle slider to 1.10
On the Red channel, move the Output sliders to 122 and 242
On the Green channel, move the Output sliders to 62 and 244
On the Blue channel, move the Output sliders to 52 and 246
Here's a screenshot of the Blue so you can see what I mean:
Then mask it on very carefully.
