Hi!
I would like to present the first spectrum I got in collaboration with my students Maximilian and Elina (both 16). It's a spectrum of 61 Cygni obtained with a LX200 10" SCT reflector, a ST-10XME and a DADOS spectrograph with a 1200 l/mm grating. The exposure time was of 3 times 5 minutes for each star and each wavelength range, so 1 h in total. I has been calibrated using an Ormalight 9W energy saving lamp and reduced with BASS.
I would be happy to get suggestions and maybe a recommendation about the easiest way to identify the lines we see in the spectrum.
Best wishes

Nice start. Identification of lines can be difficult. You could try looking at a solar atlas (several are on line e.g. http://adsabs.harvard.edu/full/1995ASPC...81...17K ) or try Richard Walker's Spectral Atlas for Amateur Astronomers, Cambridge University press where I think he used the same spectrograph as you have.

Hi,
thank you Andrew! I know about Walker's Spectral Atlas. That is indeed very useful. I'll also give a look at your link.
Some days ago I've ordered this book:

Hope this will help!
