This page should probably be moved to European Extremely Large Telescope (requires administrator) Rnt20 21:13, 13 December 2006 (UTC)
this might be a bit far fetched, but did they chose exactly 42m because of the hitchhikers guide to the galaxy? no 190.209.30.96 ( talk) 00:17, 4 May 2010 (UTC)
Actually Yes - working as part of the team doing research into making the primary mirror segments, I have spoken to people involved with tendering bids for this project. 42 meter diameter was chosen for the H2G2 reference. Thunder Krieg ( talk) 13:39, 25 February 2011 (UTC)
You may find this podcast an informative source of information http://downloads.bbc.co.uk/podcasts/radio4/material/material_20080605-1800.mp3 —Preceding unsigned comment added by 82.17.173.132 ( talk) 14:07, 11 June 2008 (UTC)
I am puzzled by the statement in the info box that the resolution depends on the target. As far as I know, the angular resolution is a feature of the airy disk which depends on wavelength, diameter, seeing conditions (turbulence, AO, detector readout time), and the spectroscopic resolution is a feature of the spectrograph (??)

When will E-ELT start contruction? —Preceding unsigned comment added by 123.24.225.130 ( talk) 00:37, 15 April 2011 (UTC)
"The start of operations is planned for early in the next decade.[14]" -- so is it around 2013 or around 2023?
What kind of question is that? 2013 is this decade not the next one. 10 years for construction with the start at the end of 2012 is what I read, so around 2022 for first light. Martin Cash ( talk) 11:45, 7 January 2012 (UTC)
Looks like first light is actually going to b 2024: http://www.eso.org/public/usa/news/eso1419/ 134.171.185.129 ( talk) 23:18, 19 June 2014 (UTC) John
Could someone please update File:E-ELT Laser Guide Star.ogv from http://www.eso.org/public/videos/eso1150c/? I don't know how to do this, and the present version shows Ursa Major in the sky. -- ἀνυπόδητος ( talk) 17:31, 23 July 2012 (UTC)
I recommend adding a list of participating countries plus the total costs of the project until inauguration in 2023 (about 1 billion euros AFAIK) — Preceding unsigned comment added by 83.82.71.89 ( talk) 08:46, 9 May 2013 (UTC)

Extremely Large Telescope – The telescope name has been updated. Please see

Extremely large telescope already exists, so we should be able to have both page (i.e., Extremely Large Telescope and Extremely large telescope).

This raises a number of issues.
Should occurrences of European Extremely Large Telescope in sources also count as occurrences of Extremely Large Telescope? I think they should.
Is the capitalisation sufficient disambiguation? I think it is.
Other opinions? Andrewa ( talk) 12:18, 28 April 2017 (UTC)

The article currently compares the ELT's light gathering area and sharpness to the Hubble. Now that the James Webb Space Telescope is in service, it might be better to compare to the Webb. The ELT has 38x the light gathering area of the Webb (straightforward calculation 978/25.4), and about 20x the resolution (0.1 / 0.005 -- see [1]). Unless there is some objection, I will update the article. -- Macrakis ( talk) 12:03, 8 November 2023 (UTC)
