This page gives an overview of the instrumentation available on the WHT and INT. It is revised bi-annually to reflect the options offered in each semester. Full information on all the listed instruments is indexed in the Manuals Home Page, and information on older instruments can be found on-line in the Obsolete Instruments section of the Manuals Home Page. A summary of the time allocation process is available here.

NAOMI/INGRID and OSCA
Prospective NAOMI/INGRID applicants should read the most recent performance summary, and prospective applicants wishing to use the coronograph OSCA with NAOMI/INGRID should read its homepage.

NAOMI/OASIS
The Integral Field Spectrograph OASIS is offered with NAOMI on a shared risks basis. Prospective applicants should read the OASIS home page.

INGRID at the Cassegrain Focus
INGRID is not offered at the Cass focus in 2004B, but is offered at Nasmyth with the adaptive optics suite. It can also be used at Nasmyth with the AO loop switched off; in this case a guide star is not needed and throughput is reduced by ~0.5 mag compared to that at Cass.

WYFFOS Long Camera
The WYFFOS long camera will be commissioned in July 2004, and subject to successful commissioning will be offered with the 2xEEV mosaic detector in 2004B, on a shared risks basis.

LIRIS
The long-slit intermediate resolution infrared spectrograph, LIRIS, is offered in both imaging and long-slit spectroscopy modes on a shared risks basis.

New Visitor Instruments
PIs planning to submit a proposal based on a new (to ING) visitor instrument should follow the procedure for New Visitor Instruments.
