Segmented mirror telescopes

Shouldn't this article make reference to the original MMT [1], which was the first active, segmented mirror telescope? The claim that NTT is the first active mirror telescope is not accurate. The MMT dates back over 25 years. Like the NTT, the MMT was an alt/az telescope. Drphysics 16:14, 20 March 2007 (UTC)

Nordic Optical Telescope

I've been researching the history of active optics for another text, and from that perspective, the current statements about the Nordic Optical Telescope seem to be a bit misleading. That telescope does have pneumatic support for the main mirror, but it was designed as a purely passive system (the mirror is still thick enough for that), see http://www.not.iac.es/telescope/tti/proptxt.html

The designers were aware that the configuration with the pneumatic support would allow to extend the system to include active optics, and such a system was installed some time in 1992 (may be starting a bit earlier, and finishing a bit after that; the article only mentions that the system "is being installed"), see http://articles.adsabs.harvard.edu//full/1992ESOC...42..311A/0000312.000.html

Given that information, I'm changing the wording in that part of a text somewhat, to what I think is a more accurate version. Markus Pössel (talk) 13:05, 5 July 2021 (UTC)

OK, since there was so little about the active optics aspect to begin with, having no details except for the largely irrelevant NOT mention seemed misleading; I have removed NOT mention here, and will see if I can add the active optics information to the NOT lemma.
