I think that the colour casting is due to the bright moon illuminating the left hand side and when the camera isnt looking at it the colour cast changes, not sure to be honest, but the exposures were all the same.

yeah it is portrait shots, two high, I just didnt think to get more foreground in the shot, not to mention that it was pitch black :-)

Unfortunately, f3.5 is the widest that this lens goes to, otherwise I would be definitely shooting wider open.
I don't think the moon is the reason for that brown cast. I haven't seen that happen with any of my cameras (several brands). What does the exif data show about exposure details for those shots? Did you set a fixed white balance for all when processing? I usually process a RAW of one from a series in a panorama to where I like it then save the settings and simply apply them to the rest in the sequence. That works well.

No polariser on the lens is there? If that happens again I would suggest holding down the exposure lock button when taking the shots and not use an intervalometer.

The Samyang 14mm F2.8 lens is hard to beat bag for buck and you can load a distortion correction lens profile to correct that. It will help get a wider and higher image.
