Steve, I have had the misfortune several times of having GEOs passing through long comet exposures. This is the first time that I have seen them in color. Very nice image. Mike

Thanks Mike, it was taken as an experiment.  They must be rather than large as brighter than I expected.  Used an 85mm lens which was good as I made a schoolboy error of forgetting to factor in the fact that we are well above the equator.  Camera was pointing at celestial equator.  This is cropped.
