Thanks guys.
Justin, I'm just using a Star Analyser 100 diffraction grating - essentially a 1.25" filter that creates a spectrum. Very much entry level but it's remarkable what you can see. Head over to the spectroscopy section of the forum and you can get an idea. Nova Del 2013 has been amazing from a spectroscopic point of view. All sorts of elemental emission lines as the gunk thrown off the white dwarf's surface in the nova outburst gets ionised by UV, X-Rays etc and then starts to emit light at specific wavelengths; then you can see the blue shift created by the ejecta coming towards us at 1000 kms ... all sorts of stuff. You can see a lot of this with the SA100,
I've got a Spectra-L200 on order for the serious stuff :-)
