Seems everyone had clear sky this weekend! More posts on here with great pictures than I can keep up with. Why not add another to the mix!?
I'm struggling to bring out the diversity of colour, and correct contrast I want in these photo's from the weekend without making them look awful.

There's quite reasonable data in the original exposures. The colour changes dramatically from horizon to zenith and I think that's a large part of my problem, perhaps an occupational hazard of using such a wide fisheye? Gradient removal would be an option, but it did vary in colour in reality.
Canon 7D @ 1600ISO
Canon 8-15mm F/4 fisheye (yeah! what a lens!

)
12 x 2 minute exposures.
Anyway, suggestions and comments on colour and contrast would be appreciated
