In recent years there has been a trend toward the automation ofmodest sized observatories, especially those involved withphotoelectric photometry. Although undoubtedly useful, there isclearly a need for more advanced instrumentation such asspectrographs. The relatively small telescope sizes places severelimits on the choice of spectrograph configuration. A fiber-fedechelle spectrograph is arguably the most suitable design forthese applications.Presented here is a brief discussion of the design philosophy andoperating principles. Both theoretical and measured performancedata for the prototype University of Queensland EchelleSpectrograph are also presented.
