Hi All,

I'm in the process of writing a high school (Year 11/12) teaching unit on the Sun, with the emphasis on observing and experimenting rather than looking up images. Is it possible for school students to see absorption lines reasonably well using a CD spectroscope? I've tried making one with no success (at seeing the lines): just a bright, glaring image surrounded by continuous spectra. Nothing like the images on the net. Any ideas would be helpful.

Thanks,

Geoff Mc
