Re: sun's spectrum

Please don't point your spectroscope at the sun at look directly in the
instrument to see the spectrum if you are using a 'Project Star'-type
electroscope. You won't see with that eye again!!

You can point the spectroscope at blue sky (away from the sun) (blue
sky--not a common occurence in Syracuse) and see the Fraunhoffer lines.

When you look at the sun's light in a spectroscope, you see the entire
spectrum. Since the sun is made mainly of hydrogen, where are the hydrogen
lines? Or the helium lines?
