AG Dra first post!

Hi
My first spectrum post to the forum, tried AG Dra last night and despite bright moonlight managed a few 600 sec shots. Not sure about the Sodium ID though as no Sodium lines are listed in the OHP 2013 observers guide for Symbiotic type stars?.

Good ! Steve
The spectral response could be improved : the continuum is more intense in the red part ofd the spectrum
The emission is He I 5876, just before NaID absorption.

Bonne continuation

Hi Francois
Yes more practice needed on the fainter stars I think and maybe more exposures to increase the signal to noise ratio!
