Calibrated using F line (hydrogen beta) and E1 line (iron) on Rspec. Spectrum and graph are then put together on PS, approximately matching the dips in the graph with the dark lines on the spectrum. Taken with 1350l/mm DVD grating and D5300.

High pressure sodium lamp spectra
Spectra of high pressure sodium lamp as it warms up, showing the collision broadening and self reversal effect due to the absorption by the cooler sodium in the outer layers. Shot using DIY spectroscope, 1350l/mm DVD grating and DSLR. Cropped to the same size in PIPP and calibrated on Rspec.
