I discovered a couple of nights ago that with my new red torch it wasn’t actually possible to read the red markers on my Lunar 100 map. So, I’ve made a new version with the markers in dark blue, which I can read with the red torch. It’s not the best solution in the world as I’ve had to mangle the original PDF, but I think it will work for me.
In the event that anyone else would like to use it, here it is.
