We present white-light and narrow-band [S II] coronagraphic imagery of the disk and bipolar microjet associated with the classical T Tauri star DL Tau and the bipolar outflow associated with the classical T Tauri star CW Tau. The STIS coronagraphic imagery for DL Tau reveal the presence of a disk with azimuthally symmetric dark lanes several hundred AU from the star, in addition to a bipolar microjet extending 6" (840 AU) from the star. Narrow-band [S II] coronagraphic imagery obtained with the Apache Point Observatory 3.5m telescope and the Goddard Fabry-Perot as well as HST/WFPC/2 R-band direct imagery demonstrate that the outflow has the emission-line features expected of low excitation HH objects. HST/STIS white-light coronagraphic imagery of CW Tau detect the approaching microjet, while the APO/Goddard Fabry-Perot imagery demonstrates that the microjet is associated with a large-scale bipolar outflow which can be traced at least 1.7' (0.07 pc) from the star.
