By replacing the 5 mirror Coud\\'e train with a Cassegrain mounted fibre-based image slicer CYCLOPS2 simultaneously provides improved throughput, reduced aperture losses and increased spectral resolution. Sixteen optical fibres collect light from a 5.0 arcsecond^2 area of sky and reformat it into the equivalent of a 0.6 arcsecond wide slit, delivering a spectral resolution of R = 70000 and up to twice as much flux as the standard 1 arcsecond slit of","authors_text":"Anthony Horton, C.
