Discoveries using the telescopes on Mauna Kea

[TomK]

rbakker - thought this would interest you. A few years ago I used the Pluto-Charon system to check that UKIRT was working properly after we'd switched from wide-field mode to Cassegrain mode (a mode in which we have specialist instruments that are used to observe only very small parts of the sky and individual objects). I was actually quite surprised to find that Pluto and Charon were easily resolved from each other despite not having calibrated the telescope's optical system.
