More Symbiotics!

[Gasman]

Hi guys

Tried some more symbiotics from Robin`s Low res spectroscopy guide. I tried eg And, ch Cyg and z And. Hopefully I`ve selected the correct star for z And as the field of view was quite full and it is showing different features in particular a strong absorption line at 494nm, poss He at 492?

Regards

Steve

I`ve restacked the 10 fits I took of z And in Autostakkert and I think it gives a better resolution?.

corrected for instrument

Cheers

Hi Steve,

Here are some other amateur spectra but the spectra vary in the emission lines depending if they are in outburst or not

CH Cyg (which was the subject of a short campaign last year)

and is currently active

BD Cam from Christian Buil's list (no obvious activity then)

Z And from Francois Teyssier's list
