HORuS is a high-resolution (R=25000) spectrograph for the 10m Gran Telescopio Canarias (GTC). It collects light at the Nasmyth focal plane, shared with OSIRIS...

FIES is a cross-dispersed high-resolution echelle spectrograph with a maximum spectral resolution of R = 67000. The entire spectral range 370-830 nm is covered...

The Intermediate Dispersion Spectrograph (IDS) is a long-slit spectrograph which sits at the Cassegrain Focal station of the 2.5m Isaac Newton Telescope and is...

IO:O was originally equipped with a Fairchild 486 CCD detector. However, this was found to have degraded during storage resulting in poor blue Quantum...

The Isaac Newton Telescope (INT) has a 2.54-metre primary mirror with a focal ratio of f/2.94. It uses a polar-disc/fork type of equatorial mount. Instruments...

LCO's Network of Robotic Echelle Spectrographs (NRES) will be six identical high-resolution (R~53,000), precise (≤ 3 m/s), optical (380-860 nm) echelle...

The Liverpool Telescope is a 2 metre diameter optical astronomical telescope, constructed especially for robotic use. The telescope is especially to study...
