Stars over and through reeds

I took some night photos of stars over some reeds.  All photos taken with 30s exposure, maximum aperture, on a tripod.  ISO was varied (200 - 1000) to adjust brightness.  In some pictures it appears that stars are shining through the reeds ...
This one captures the big dipper asterism/constellation over some reeds


You can see the stars "through" the reeds most clearly in this picture.  I suspect this is because when the reed sways in the wind, it allows some starlight to reach the camera; the star is so bright compared to the light reflected from the reed that the star dominates the pixels, making the reeds look transparent.
A brighter image (higher ISO).  Moon-shadows visible on the road and fence.
Looking up to see more stars

A less bright image, the reeds are blurrier b/c it was windier during this photo 








Self portrait in the moonlight.  The first image has been brightened, second is the original.  2.5 s exposure b/c I couldn't hold still for 30s.
