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
spectroscope. 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.

We have found looking at a specular reflection of the Sun from a distant
chrome car bumper, windshield, or other highly polished but convex surface
allows one to safely view solar spectra with the Project Star spectroscopes.
