Abstract (from CDS):

ISOGAL is a 15µm ISOCAM survey of ∼12deg2 in the Galactic Plane interior to |l|=45°. In combination with IJK data from the near-infrared southern sky survey DENIS, the ISO images allow the first detailed study of stellar populations throughout the inner Galaxy. We present preliminary results from a test observation at l= -45° with 6" pixels and completeness limit 8mJy. Of the ∼3000 sources deg–2 detected, about half are KM giants, seen through extinction of up to Av∼30, while most of the remainder are probably dusty young stars. Although away from bright IRAS regions, the field displays spectacular emission features, and, unexpectedly, a number of regions which are optically thick at 15µm. The dark regions are presumably dense filaments with Av>25.
