V771 Sgr (Be) Alpy600/T60

Post by Daniel Dejean »

Hello All,

As part of our setup qualification for low resolution spectro at T60/Pic du Midi :
- T60 : NewtonD600/F2000
- Alpy 600 with Kepler corrector (ref : KE244 à « La Clef des Etoiles »)
- main cam : Atik428EX bin1x1
- guide cam : Atik314

you will find below our result on V771 Sgr target.
Spectral type : B3 on Simbad / Oe on Bess / Magnitude V : 8.76
May be because of low luminosity there is only 2 observations reported on the BESS data base with only one in low resolution from C.Buil at OHP 2011 C9+Lisa+Atik314L .
Compared to that reference there the Lisa result shows a better resolution (not a surprise…).
The overall spectra picture appears very similar and no significant problem is identified with our configuration.

Many thanks for any comment or advise.
Cheers,
Daniel
