Resumen:
NGC 6193 is an open cluster embedded in an HII region (RCW 108, Rodgers
et al. 1960) located 15^' eastwards of NGC 6188. The later is a bright
rimmed cloud that stretches over 30^' in the north-south direction, and
marks the interface between RCW 108 and nearby dark clouds. RCW 108 is
being powered by the multiple O-type star systems, namely HD 150135-HD
150136 (Niemela & Gamen 2005) in the core of NGC 6193. The UV
photons emitted by these stars may drive photoinization-induced shocks
into the nearby molecular clouds, possibly originating the well studied
infrared cluster RCW 108-IR (Comerón et al. 2005, and references
therein). In this work we describe the morphology of the distribution of
the photoionized and shock-excited gas based on Hα, [O III] and [S
II] images, ^{13}CO observations, and infrared data (2MASS, MSX).
