Scientific paper

During a survey for faint H-alpha emission-line stars in Tau, a pair of on-line, off-line frames of the L1551-HH30-HL Tau region was obtained with an 800 x 800 CCD detector mounted on the Burrell Schmidt telescope at KPNO. Potentially important optical features unnoticed in most previous studies are discussed. In the L1551 core region there is a cluster of HH objects W of HH28 which on the average are larger and more diffuse than those which are closer to the source IRS5. In the SW and NE corners of the 20-arcmin field, new outlying HH objects are found. The evidence favors association with the second FIR source to the NE of IRS5 (L1551NE).
