I think you can see absorption lines in the suns spectra... There were
these cheap transmission "spectrometers" made by the STAR project.
Of course you need a sunny day! Something you can't plan on here in
Buffalo in the winter.

Subject: [tap-l] absorption spectra
In my high school astronomy class, I will be discussing light and
spectra soon. I wish to do a lab/activity where students can analyze
various light sources with a diffraction grating. It is easy to show
continuous spectra with a candle or light bulb, and emission spectra
with gas tubes. I am looking for a way to show an absorption spectrum.
In the past I had students use colored filters to cover an incandescent
light bulb. This sort of mimics the atmosphere of a star.
Does anyone have other ways to show absorption spectra using simple
