Encouraged by the successful survey of molecular outflows in the K' band by Hodapp (1994), several groups in America and abroad are carrying out similar surveys of these objects in the molecular hydrogen v=1-0 2.12\mum emission. The 2.12\mum line traces in most cases the shock excited gas, avoids too much contamination from the continuum emission and therefore delineates fainter structures than the broad band filters. We present wide field observations of two molecular outflows, LkHa234 and S187, taken with new infrared camera at the Fred L. Whipple 1.2m telescope. The images were taken at the 1-0 2.12\mum and 2-1 2.25\mum molecular hydrogen lines, plus continuum at 2.22\mum. The combined images cover a field of view (FOV) of ~ 7\arcmin. The LkHa234 images concentrate on the East side of the flow, and are complementary to the work by Schultz et al (1997). Our images show a more rich structure of shock excited gas, and the perhaps the presence of a second jet. Similarly our S187 images with a larger FOV than those of Salas et al. 1997, indicate the presence of a counter-jet arising from the NIRS 1 source, and perhaps another jet centered 4\arcmin NW away.
