V Sge, HM Sge, St HA 169 and more...

Hello to everybody,
here are some results taken with the newton 8" and the DADOS, after a couple of clear nights. Although V Sge is not included in the symbiotics program, I remember this star from the very far nights of visual observing... and the spectrum is very different if we compare it with other symbiotics like AG Peg or T CrB. It remembers more a nova-like very advanced nebular phase (but the [O III] is missing!).
HM Sge... although it is quite faint for my 8", the spectrum recorded is spectacular and full of emission lines. It would be a nice job if I try to identify all these lines. Some are easy, of course. The others... well, we will see.
St HA 169... I programmed the telescope to take many spectra because it is very faint, but a problem guiding only avoided me to take two spectra. Well, maybe next time...
Greetings
Fran
