The ACS survey of the Orion Nebula offers an unprecedented opportunity for the study of outflows in this region. The F658N filter used transmits the ubiquitous HI line at 6563 A and the common low ionization line of [NII] at 6583 A, thus rendering most low density gaseous components visible. We have found many types of outflow from micro-jets of about 100 AU from some proplyds to parsec scale shocks arising from embedded sources to the southwest of the Trapezium stars.
