James, you need to learn how to stretch your images!

I had to reduce the filesize in order to post so I lowered the resolution, sorry about that.

Sorry, I meant a dynamic stretch of the data range, so that the fainter features come out. This is done in post-processing.

Can you point me towards a guide or resource describing how this is achieved? Sounds interesting.
