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:

Re: T CrB symbiotic star (the blaze star)
Hello,
I have tried this star when I wait a FS Cma was more high in the sky.
With : T500 + ESHEL :
You can find more detailed spectrum at http://www.astrosurf.com/charbonnel/Tra ... 01_918.png
And FITS files at http://www.astrosurf.com/charbonnel/Tra ... 01_918.zip

Re: T CrB symbiotic star (the blaze star)
C'est un résultat spectaculaire à cette faible luminosité (mag 10.1) !
Un crop sur Ha : L'absorption centrale légèrement décalée vers le bleu (comme dans la plupart des symbiotiques) est clairement visible.
Bonne continuation Stéphane.
