I have to say, even though I've been into astronomy (on and off) since the late 80s I did not know Mercury had a plasma tail that can be visible on photos, but it seems to be true, now I want to take my own image of it!
That orange streak is Mercury with its glowing sodium plasma tail, passing in front of the Pleiades cluster.
Impressive capture by Dr Sebastian Voltmer.
