The zodiacal light is the pale white cone of light slanting upwards
to the right from the horizon. The Milky Way crosses the image slanting
in the opposite direction. Orion is at upper right. The stars have
trailed slightly during the time exposure.
Sunlight scattered by untold millions of interplanetary
dust grains extending out to the orbit of Jupiter produce the soft
glow. The grains are up to 0.3mm or so across and are miles apart.
This is the season in the northern hemisphere to look for the glow
about an hour after sunset . The cone lies along the ecliptic,
the approximate plane of the Solar System. Close to the Spring
Equinox the ecliptic and the cone point most strongly upwards.
You will need a clean sky free
of artificial lights. The lower your latitude the easier it
will be to find it.
