reduced spectrum

Forums Spectroscopy Nova in M31 reduced spectrum

Here is the reduced spectrum.  (red, filtered to R~300 resolution)

mag ~17 is the faintest target I have attempted with the ALPY600 setup and the SNR is very low. The broad H alpha line is obvious though and other Balmer lines are present too. I have also marked the Fe II curtain lines though they are only marginally detected above the noise.
