This group is focused on supporting amateur astronomers interested in Spectroscopy. Our aim is to provide resource material and assistance to both the beginner and the more experienced amateur. A Littrow spectroscope Kit - Spectra-L200 has been designed for the benefit of the members. We have also commissioned a custom designed highly reflective slit plate - 3 pinholes/ 9 slit gaps to further assist the members.
Check out the files area for more details on spectroscope designs.

We also provide an ongoing discussion forum for Stephen Tonkin's "Practical Amateur Spectroscopy" book, as well as
"Astronomical Spectroscopy for Amateurs" and
"Grating Spectroscopes - How to use them", all published by Springer.
