Herbig-Haro 1 with UFTI
Results from ORAC commissioning with UFTI
A true-colour image of the Herbig-Haro bow shock HH 1.
The red and green channels
show line emission from molecular hydrogen (2.122 microns) and
Fe+ (1.644 microns); the blue channel shows continuum emission
associated with nearby stars and nebulosity. The high-excitation Fe+
features contrast spectacularly against the lower-excitation molecular
shock regions in this protostellar flow. The figure illustrates the
sort of image quality (in this case ~0.6") and standard of on-line
data reduction one can routinely expect from UKIRT, UFTI and the ORAC
acquisition/reduction software available at the telescope.
