Near-infrared images of the low-mass star formation region associated with the Central Source of the Herbig-Haro objects 1 and 2 are presented. Several new HH-type condensations are found in the vicinity of the previously detected radio source thought to power the HH 1-2 system. The central condensation is found to have three components, two of which change their position as a function of wavelength. The whole region resembles a projected ovoidal cavity and seems to be dominated by a combination of reflected light from a young star and material shocked by a powerful stellar wind. New infrared sources associated with a nearby H2O maser and the HH-3 object are also discussed. While these sources are obviously part of a large-scale star formation structure, they seem to be unrelated to the HH 1-2 system.
