Paper Abstract

We present an inexpensive (<US$500) and easily replicable integral field unit for use on small aperture telescopes. Based on a commercial small spectrograph (SBIG Self-Guiding Spectrograph) and a 37 optical fibre bundle integral field unit with each fibre having 50μm cores and a pitch of 125μm. It has an overall field-of-view of 40 arc seconds (2.6arcsec/core), a resolution of 9Å from 3995Å to 7170Å and an average system efficiency of 9%, yielding a signal-tonoise ratio of 10 for a 20min exposure of a 13mag/arcsec2 source. Still in commissioning, we present first light observations of Vega and M57.
