Details:
Most images of Mercury's tail use a sodium passband filter to increase the contrast but the sky was so transparent at this altitude that this was not necessary here. This enabled me to get a single unfiltered image which shows the yellow tail and the blue reflection nebulosity around the Pleiades.
