I just checked mine and Hugh’s spectra from 23rd March in the Nova Cas 2021 thread. The graphed spectra are calibrated in wavelength with a linear X axis and the Balmer (and other line) wavelengths are correct and consistent between the two spectra

Mike’s spectrum image is not calibrated in wavelength.

Prism spectra are very non linear with the short wavelength end significantly stretched and the longer wavelengths compressed
