Two recent works have found that the radio continuum source VLA 2, towards the centre of the CO outflow, is actually a multiple system of young stellar objects (YSOs). We imaged a field of 5'x 5' centred on HH 223, which includes the whole region of the quadrupolar CO outflow with narrow-band filters centred on the [FeII] 1.644mum and H2 2.122mum lines, together with off-line Hc and Kc filters. Our aim is to study L723 in the near-infrared and look for line-emission nebulae associated with the optical and CO outflows. Description: The image mosaics obtained with the instrument LIRIS (Long-Slit Intermediate Resolution Infrared Spectrograph) at the Williams Herschel Telescope are in the images directory in the Flexible Image Transport System (FITS) standard.
