Page conflates two different spectrographs
[edit]This page mixes up information about the ESO's Coudé Spectrograph in Chile, and the Coudé Spectrograph at the McDonald Observatory in Texas, developed by Robert G. Tull. (Coudé is not part of his name; it is French for "elbow," because a Coudé focus reflects light out of a telescope at a 90-degree angle. See the "Coudé" section of Reflecting telescope.)
Since a number of equatorially-mounted telescopes have used the Coudé focus to direct light to spectrographs, this page might be re-written to describe Coudé Spectrographs in general, using the ESO one and the McDonald Observatory one as examples. SiimaTamba (talk) 12:24, 10 December 2024 (UTC)
