Top panel: the YSOs within the Magakian 77 reflection nebula are identified in this Two Micron All Sky Survey (2MASS) K-band image, and their properties are listed in Table 1. H6-28 is Haro 6-28, and 2M is 2MASS J04355760+2253574. FF Tau is outside the field to the west. North is up, and east is left. Bottom panel: a J-H vs. H-K color–color diagram of 10 of the sources in the HP Tau multiple system. The dwarf and giant loci are from M. S. Bessell & J. M. Brett (1988), and the reddening lines are from G. H. Rieke & M. J. Lebofsky (1985). The abbreviations refer to the names in Table 1.
