Lou,
This was a single image, so there is no processing done on it yet. The temp was 60F last night and I had not been running it that long. I'll have to see if all images have it, or if it showed up at some point.
In the past, I saw it in one set of images after processing, but not in the raw image itself.
Hopefully it was just a fluke and the next session goes better.
