was your white balance fixed or on auto? there's a fair bit of variation in the night sky background colour which could be airglow but seems to change a bit more than i would expect for that?
cheers

Thanks for commenting Phil. I was hoping you'd pick up on this post as I need some (a lot of) help.
I read your book cover to cover a couple of times but couldn't find much in term of processing.
As you've picked up there are still a lot of things wrong with my processing. Noise, green cast and color balance issues.
My white balance is set and fixed to Daylight. ISO3200 15s subs. I shoot in RAW full frame. Color Space AdobeRGB (not sRGB). There are only two modes.
I use Adobe Lightroom 4 (LR4) and LR Timelapse (LRT). I have posted in the bug report section of the LRT forums but the bloke is on holydays at the moment so I'll wait.
I adjust the colors in LR4 .It uses Camera raw 7. I had to use the temperature, tint, shadows, exposure sliders to tweak the histogram. It is not ideal but these are the only parameters that are successfuly saved to the XMP files and read back by LRT.
The Tone curves (per R,G & B Channels) are not read back in LRT so it doesn't work when I interpolate and create all the keyframes in LRT. The issue being that even if you increase the frame density the color balance does change during the night and the histogram 'flickers' blue/green/red in between so you see that change of colors from one frame to the other. Could also be background color noise which I haven't taken care of.
So that's what I'm still to work out. Green cast and proper color balance. Do you use LR4/LRT? I have CS6 on pre-order coming mid-may or about. I'm hoping Bridge CS6 will have he functionality to Tone Curve individual Channels. CS5.5 doesn't do it at this stage.
If you have an easy solution or how to I'd love to hear about it.
