Thanks for the reply Merlin.
I did find an Amici Prism unit in Germany a while back but the Australian agent quoted me about $600.00. Too rich for me.
I had hoped that a Transmission Grating might be the modern and cheaper equivalent to the direct vision prism.
Today I have ordered a copy of "Astronomical Spectroscopy for Amateurs" to try and learn the differences.
Michael.
