The optical collimated flow HH 1050 (L 988a) is studied. Observations with the 2.6-m telescope and data from catalogs and surveys, including the archive of the Hubble telescope, are used to examine its morphology and to confirm the bipolar nature of the flow with spectral data. The distinctive feature of the flow HH 1050 is that it propagates within a wide cone with an aperture angle of about 30-40° and contains both moving condensations and shocked cloudlets. The source of the flow is one of the components of the binary star IRAS 21007+4951 (WISE J210222.70+500308.3). Other young stars in this region are also discussed.
