 The fringing wasn't present on all images, only some batches, mainly those with a full moon, the initial batches, which I dumped due to lack of contrast and interest, were taken with the moon partially obscured.

At some point I turned on the shutter delay which delays the shutter releasing after the mirror has lifted. I don't think that has any bearing on this phenomenon, with an 8 second exposure any vibes from the mirror clanking up would be irrelevant.

The in camera high ISO noise reduction was set to normal. The screen grabs were from an image which hadn't had any processing in Lr except the import process.

I will take a couple of screen grabs of the processed image...
