Terry,
My goodness, look at all those spectral lines. You must have enjoyed identifying them.
That spectrograph of yours is a really serious instrument, as I have just realized. I haven't followed the progress of amateur spectroscopy over the years, but I may be able to suggest some really weird and bizarre extragalactic targets that have decently high surface brightness, as I do a lot of scanning of galaxies data and galaxies papers.
cheers,
Robert
