Talk:Extremely large telescope

This article needs a reference for the claim that "An extremely large telescope is a telescope of more than 20m diameter". Thue | talk 20:55, 13 December 2006 (UTC)

Amendments to the lead, diameter and bigger than ELTs[edit]

"Telescopes for other wavelengths can be much bigger..." Since the cited sources define the aperture of an ELT in the range of 20m to 100m, (and I amended the lead accordingly after adding an alternative URL to the previously removed source), it seemed confusing to mention the 100m-Green Bank Telescope as an example for a much bigger telescope. Instead, I replaced it with the Arecibo Observatory. In addition, I changed the above statement to "Telescopes for radio wavelengths can be much bigger", since they are all radio telescopes (please verify) -- Cheers, Rfassbind -talk 19:02, 10 May 2015 (UTC)

Move discussion in progress[edit]

There is a move discussion in progress on Talk:European Extremely Large Telescope which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 09:45, 21 April 2017 (UTC)

The renaming is official. I wonder if we can move this article to Extremely large telescopes as it describes a class of objects. --mfb (talk) 14:26, 14 June 2017 (UTC)

Looking for more recent versions of the web pages would be ideal, but for now at least we have archived versions. --mfb (talk) 15:59, 26 September 2017 (UTC)
