Spectrum of the Great Nebula in Orion (M42)

Description

December 15, 2023.  I took this 60 second exposure of M42 with my C5 f6.3 scope with the ALPY 600 spectrograph attached using my ZWO ASI533MM Pro camera and SkyWatcher EQ6-R Pro mount.  It reminds me of a calibration lamb image.  I did not bother to calibrate the image against my camera response but did try to calibrate it to hydrogen Balmer lines as best I could.  I think there are a couple of oxygen lines quite near 5000 angstroms on the curve as well.
