Examples outside Hawaii?

I've just added mention of the Subaru Telescope next door to Keck, and the future TMT is already mentioned. Those are all on Mauna Kea, though - what are good examples outside Hawaii (e.g. US southwest, Chile, Canaries)? Does Hobby-Eberly in Texas have Nas decks? GTC in the Canaries? SALT in South Africa?

=Modified Cassegrain or Newtonian?

AFAIK, a Cassegrain is defined as having a convex secondary. Would this not make a Nasmyth telescope (as opposed to a Cassegrain with an image plane at the Nasmyth focus) a modified Newtonian as opposed to Cassegrain? Perhaps the confusion could be explained by the fact that some professional Cassegrains and Three Mirror anastigmats having image planes at the Nasmyth focus. — Preceding unsigned comment added by 195.213.16.228 (talk) 10:01, 23 January 2024 (UTC)[reply]
