Telescope Instrumentation

The INT and JKT are equipped with a restricted set of instruments that match the capabilities of the telescopes whilst satisfying the requirements of a large fraction of users. The number of instrument changes on these telescopes is kept to a minimum to reduce costs and increase reliability. The design of the WHT allows much greater flexibility, since it is straightforward to switch between the Cassegrain and the two Nasmyth focal stations, and a much greater variety of instruments may be left on the telescope. A broad functional division between the WHT, INT and JKT is as follows:
 

 WHT
 
• Spectroscopy and spectropolarimetry over a wide range of resolving powers
• Multi-object spectroscopy
• CCD imaging (faint objects, high spatial resolution)
• Infrared imaging
• High-resolution imaging and other projects in a laboratory environment
• Fabry-Perot imaging spectroscopy


INT
 

• Intermediate- and low-dispersion spectroscopy
• CCD imaging


 JKT
 

• Spectroscopy of bright stars
• CCD imaging

 
The table below summarises the common-user instruments which were available during the period 1997.
