The red IGRINS-2 spectrum with and without labels

The IGRINS-2 red-arm spectrum of NGC 7027, one of the visually brightest planetary nebulae whose complex gas layers make it an interesting first light target for IGRINS-2. The spectrum measures light from around 2.05 µm to 2.40 µm. The bright lines in the rainbow are like the fingerprints of the gasses present in the nebula.
