Lovely colours. How did you get the glow in the stars to that degree? Some sort of filter or white balance option?
No filters, I use a technique called "ETTR" or "Expose To The Right" - meaning that I purposely overexpose the image so that the histogram is as far to the right as possible without blowing the highlights - normally shown as flash areas on the LCD screen of the camera.
When you then bring back the exposure in Lightroom (or whatever) you have captured as much information as possible - whack the contrast all the way up and you are half way there. The is tweaking until you get the right colour balance.
I'm writing a guide to put on my website. I'll let you know once it is up.
