About this image

The detrioration in the weather means that it could be a while before I can observe Nova Cas 2021 again. So I thought it was a good moment to thread together the spectra that I've already captured of this slow nova, zooming in on the short wavelength end of the spectrum. The brightness of the nova has been very stable with signs of an increase again in the last week or so. Sit back and enjoy the transition from a helium- to an FeII-nova.
