Description

Spectrum of Nova Persei 2020, captured using a Star Analyser 100 grism setup on a C8 at f/6.3. The spectrum was captured during the decline of this classical nova at a magnitude of around 9.5-10, which I believe represents the limit of what is possible with this setup. At its climax, the nova was around 8-8.5. Note, the spike around 7500 Å is, at least partly, an artefact due to a faint star on top of the spectrum. Also, the H-alpha emission was somewhat overexposed.
