Hi,
[Correction] These are most likely crepuscular rays, not zodiacal light.
#1.
Crepuscular rays along the ecliptic at sunset (click for larger version). Stack of 99 frames shot between 18:59 and 19:08 in Brisbane with a Canon 5DmkII + 24-105 mm f/4L @ 24 mm on a fixed tripod.
The bright white streak is the "star trail" left by Venus.
#2. (B&W) Crepuscular rays along the ecliptic again last night.
I missed most of it in my rush to get set up, so I had to manipulate the colours and convert to B&W in order to increase the contrast. The zodiacal light is a bright, wide bar rising up from the horizon (with a small darker region in the middle). Venus can be seen in the lower crepuscular light ray. The bold white line just above the trees on the right side is a patch of cloud.
Cheers,
Dave
