Raw spectrum obtained with IGRINS-2 for the planetary nebula NGC 6302

Raw spectrum obtained with IGRINS-2 for the planetary nebula NGC 6302: on the left side is the H-band and on the right side is the K-band. The complexity of the emission is clearly apparent, with numerous broad and narrow emission lines from the source on the top of some sky lines. The top left inset is the image from the slit-viewing camera (the IGRINS-2 slit is the black line in the middle of the planetary nebula), showing the exact position where these data have been taken. Acknowledgment: This spectrum was collected using the Immersion Grating Infrared Spectrograph 2 (IGRINS-2) developed and built by a collaboration between Korea Astronomy and Space Science Institute (KASI) and the International Gemini Observatory.
