  Throughout the last decade sensitive infrared observations obtained by the
Spitzer Space Telescope significantly increased the known population of YSOs
associated with nearby molecular clouds. With such a census recent studies have
characterized pre-main sequence stars (PMS) and determined parame- ters from
different wavelengths. Given the restricted Spitzer coverage of some of these
clouds, relative to their extended regions, these YSO populations may represent
a limited view of star formation in these regions. We are taking advantage of
mid-infrared observations from the NASA Wide Field Infrared Survey Explorer
(WISE), which provides an all sky view and therefore full coverage of the
nearby clouds, to assess the degree to which their currently known YSO
population may be representative of a more complete population. We extend the
well established classification method of the Spitzer Legacy teams to archived
WISE observations. We have adopted 2MASS photometry as a standard catalogue for
comparisons. Besides the massive embedded cluster IC5146 we provide a multiband
view of five new embedded clusters in its surroundings that we discovered with
WISE. In short, the analysis in- volves the following for the presently studied
cluster sample: (1) extraction of 2MASS/WISE/Spitzer photometry in a wide
circular region; (2) field-star decontamination to enhance the intrinsic
Colour-magnitude diagram (CMD) morphology (essential for a proper derivation of
reddening, age, and distance from the Sun); and (3) construction of
Colour-magnitude filters, for more contrasted stellar radial density profiles
(RDPs).
