You know, I remember over 20 years ago, borrowing a hand held prism spectroscope from our Science department here at work (they have moved now) for the specific purpose of trying it at the eyepiece of a telescope.

For the life of me, the rest is a blank............I can't remember whether I tried it, didn't try it or it didn't work(my telescope at the time was not driven and was a pile of junk).

As a kid, I also recall playing around with replica gratings and prisms.I was never successful at seeing any star spectra.

Surely, my fellow spectra lovers, there is a cheaper way to see the spectra, use some form of chart as reference, and be able to simply identify some stars make up without spending hundreds............or am I wrong in assuming this?

Would a hand held(converted to couple to an eyepiece) prismatic (with fixed slit)spectroscope work on a large, fully driven telescope???
