We present the results of a narrow-band infrared imaging survey of a narrow strip (12' wide) around the Galactic equator between 6{deg} and 21{deg} of galactic longitude aimed at detecting field stars with strong CO absorption, mainly late-type giants and supergiants. Our observations include follow-up low resolution spectroscopy (R=980) of 191 selected candidates in the H and K bands.
