     It is an interesting exercise to try to identify the stronger features
in Doug's spectrum.  Among the obvious stuff is:  the strong narrow line
near the left side at 5890A is of course the sodium D lines (a pair that
are a few Angstroms apart).  The broad absorption between 6200A and 6300A
is a TiO band with the bandhead at 6158A.  The right line of the pair
near 6600A is H-alpha, but I can't identify the left one.  The strong line
at the right edge of the panel is the bandhead of the terrestrial B band
due to molecular oxygen (lettered 'B' by Fraunhofer just as the sodium lines
are D, calcium H & K lines in the blue, etc.).

Brian:
My plan for future spectra is to give a better description of each spectrum and identify as many features as possible.  This first spectrum was an exercise in web page creation.  I am planning on providing a text file with each spectrum if someone wants to analysis it further.  I also want to include some of my low resolution (~ 60 Angstrom) spectra on the page. I can get objects to 10th magnitude with my low resolution spectrometer.  In the near term,  I need to get better at web page creation!

Doug
