I know that you can measure redshift from stars by looking at the shift in there balmer lines or more generally there line absorption spectra and seeing how far these lines have shifted from actual balmer lines or line absorption spectra of the same elements on earth.
But how would you calculate the red shift of type 1a supernova when you don't have any absorption lines because they are not surrounded by hot gasses of known elements?
