Any idea what the vertical streak is near the top-most bright star of Pleiades?

 

Modded Canon T3i.  About 5 hours of lights (3 minute individual exposures).  ISO 800.

The pleiades has a lot of streaky nebulosity.  I am looking at your photo and see one vertical streak through the star (slightly to right of center of the star) and another a bit to the right of that.  I was looking at other Pleiades photos and saw the same streaks - I think you just caught some of that streaky nebulosity.  There are plenty of other photos on CN of M45.  The deeper you go, the more nebulosity you can see.

M45 is packed full of that streaky nebulousity- have a look at me RASA image- it is full of the stuff https://www.astrobin...ection&nce=2139

 

That's a nice image- I like the blue very much.
