The GlobalJetWatch project (www.globaljetwatch.net) will place small (0.5-metre) commerical telescopes
in four schools around the world. Each telescope will be equipped with a custom designed spectrograph,
currently being built by the Astrophysics sub-department of the University of Oxford. The scientific goal
of the project is to provide continual monitoring of a rosetta stone object, the micro-quasar SS433. In addition,
the project has a significant out-reach element, aiming to involve school children on four-continents
in front-line astronomical research. The spectrograph is a fibre-fed fixed format cross-dispersed echellete
design providing R~6000 spectra from 4300-8500 in a single exposure. The spectrograph is built almost
entirely from off-the-shelf components. The four GlobalJetWatch sites (Australia, India, South Africa,
Chile) will be commissioned in 2008/09. Here we present the baseline design of the spectrograph, and
initial results from the prototype on-sky commissioning in Oxford.
