If you are looking for an interesting and (exotic) target for your students with your setup how about the microquasar SS433 (the lawn sprinkler)
It shows several broad emission lines from jets, Doppler shifted by varying amounts as it spins. Here is a project sheet from Leicester University UK
and an example spectrum I measured using a Star Analyser prototype grating back in 2004 but never got round to repeating to see the variation in the line positions.
Found this on a yahoo group. We should be able to see it
NEQ6 mount, C6 telescope with skywatcher guide scope for moving around with Starlight SXVR H9 main camera and SX auto guider.
Celestron C9.25 and WOZ 72 in dome with atik 460 camera and a Co-star for guiding with alpy for spectroscopy.
MCT5 with SE mount and SXVR MX 916 camera and star analyser for spectroscopy
