Isaac Newton Telescope
The Isaac Newton Telescope (INT) has a 2.54-m diameter primary mirror. It uses a polar-disc/fork type of equatorial mount. Instruments can be mounted either at Cassegrain or Prime focus, offering the possibility to carry out both intermediate-low dispersion spectroscopy and wide-field imaging.
Detailed descriptions to operate the telescope and instruments can be found the in the instruments web pages and links therein.
Changing from WFC to IDS and vice-versa requires daytime engineering work. When WFC (mounted at Prime focus) or IDS (mounted at Cassegrain focus) are in use no other instrument option is available.
Information to apply for observing time can be found at Applying for Telescope Time.
For preparing and planning observations, read the information at Planning Observations.
Observing at the INT
Visiting observers at INT should have considerable end-to-end observing experience with medium-sized telescopes and be familiarized with the instrument, telescope and health and safety documentation prior to the starting of the observing run. As there is no Telescope Operator (TO) at the INT, observers are responsible for all aspects of telescope and instrument operation during the night. A detailed introduction to the telescope and instrument is given by the INT Support Astronomers (SA), who will contact the PI in advance, to confirm the instrument configuration, discuss the observing plan, etc. The SA will be at the telescope from the afternoon until about midnight of the first day of the run and will be reachable at ORM Residencia during the whole first night of the run. Observers with little (or long ago) experience at INT are encouraged to spend the previous night to the start of their run at the telescope. Please contact your INT SA to coordinate this.Service mode observations for regular INT programmes
PIs of regular proposals at INT now have the possibility to request service observations for their IDS or WFC programmes in the new scheme of INT Service-mode observations.
For any question do not hesitate to contact your INT SA, Instrument Specialist or INT Manager.
