It is one of the Isaac Newton Group of Telescopes (ING), which also includes the William Herschel Telescope (WHT).
INT was rebuilt at ORM in 1984 after earlier operation
in England that began in 1967.
INT is currently not carrying out observation, currently dedicated
to the commissioning of the new a high resolution spectrograph, HARPS3,
for the Terra Hunting Experiment.
As of 2/2026, the telescope has been prepared
