The design is a high-throughput fiber-fed echelle. It is cross-dispersed, yielding a passband of 390-910 nm. It accommodates 3 optical fiber pairs (science+sky) and offers 3 resolutions, 60K, 48K and 30K. TRES will supersede the current Echelle spectrograph at the 1.5m, resulting in much greater observing efficiency (see the links below).
Please check with Dave Latham at CfA before the start of each trimester to coordinate your observations.
