The objective of this supplementary discretionary time proposal is to perform
ISOCAM CVF spectro-imaging of (most of) the field in the M16 "Eagle nebula"
which we earlier mapped in LW2 and LW3. The goal is to establish the physical
nature of the emission, including in a mysterious extended feature discovered
in our LW3 image located near (but outside the extent of) the main "elephant
trunk" in the "Hubble field" in M16.
