That's very great, Joan.
Congratulations for the NOUT and the spectrum.

The brightest star of the field is TYC 5121-549-1 V =10.65

Nice spectrum, Christophe.

A faint transcient was detected in Ser ( http://www.cbat.eps.harvard.edu/unconf/followups/J18385851-0351482.html ) and identified as
a nova ( https://www.astronomerstelegram.org/?read=17292 )

The current magnitude V is ~12

Note the complex profile of H beta and He I 5876 with 3 apparent peaks.

This spectrum is a textbook case showing that H alpha is far to be the best Balmer line for astrophysics studies : too much ...
