Has anyone played with the SDSS data?
I stumbled on this:
http://www.sdss.org/dr5/algorithms/s...tes/index.html
and thought it may help when trying to identify lines (for us L platers

).
They also have spectra available apparently (I haven't tried a download). I think they are plots not images though

.
Here's another useful page of link from the CSIRO:
