  Jets and outflows are associated with young stellar objects across the
stellar mass spectrum, from brown dwarf protostars to massive, Ae/Be stars.
Frequently, the jet morphology is spatially discontinuous because of the
temporal variability of the ejection from the driving source. Images covering a
wide field of view around the jet driving-source are useful to map the
large-scale jet emission and to explore the mass ejection history. The aim of
this work was to search for large-scale optical Herbig-Haro (HH) objects lying
in a wide field around a sample of IRAS sources, candidates to trace young
stellar objects. Deep, narrow-band images through the H$\alpha$ and [SII]
emission lines, and through an off-line continuum filter, covering a wide
($\sim15'$) field around the IRAS targets were acquired. The images in the
three filters were analyzed to identify shock-excited line emission (i.e., HH)
in contrast to scattered line emission. New images of a sample of fifteen IRAS
sources, obtained in an homogeneous way are presented. HH emission was detected
in six fields, and the astrometry of the knot features is given. The nature of
the extended emission as scattered emission around nine of the IRAS targets is
confirmed. For seven IRAS sources, with unclear optical counterpart, a more
plausible counterpart is proposed. A refined value of the source distance is
reported for seven targets. An update of the main data available for each of
the sampled fields, including images from public data archives, is also
presented.
