Caption: NGC7027, a planetary nebula in Cygnus, is one of the spectral calibration targets for the infrared spectrometer. Inset is a 1.88µm spatial image of NGC7027 that was reconstructed from a sequence of 50 observations taken during the EPOXI Cruise Cal on 9 January 2008. The spectrum of NGC7027 is seen (increasing wavelength to the right) nearly centered in the spectrometer slit.
