T CrB is well positionned in the sky after midnight. It is a recurrent nova and is kind of easy to get.
Here is a spectrum with very long exposure [so I could sleep...
] on T CrB with LISA spectrograph and Televue 85mm refractor:

C'est un résultat spectaculaire à cette faible luminosité (mag 10.1) !

L'absorption centrale légèrement décalée vers le bleu (comme dans la plupart des symbiotiques) est clairement visible.
Bonne continuation Stéphane.
