I chanced upon an interesting paper in the Astrophysical Journal about a wide angle camera deployed to Mauna Kea for a few days in 1997 that discovered new zodiacal dust bands in visible light. A link is here.
Since CONCAMs are really wide angle and deployed for a much longer time, perhaps CONCAMs images can be used to discover more and fainter filamentary bands of zodiacal light? CONCAMs are really good at detecting diffuse, extended, long lasting faint stuff (like thin clouds), and frequently see zodiacal light. See: http://nightskylive.net/asterisk/viewto ... t=zodiacal
and http://antwrp.gsfc.nasa.gov/apod/ap020915.html .
BTW zodiacal light is sunlight reflected by small dust particles that orbit the Sun.
