"Day One"

"Day One instrumentation " and another appearance of Day One, capitalized, are mysterious.--Wetman (talk) 00:13, 26 July 2009 (UTC)

Aperture size

I'm not an expert on telescopes or on the archaic US system of measurements, but aren't telescope apertures usually given in inches, not ft/in? As in, the 200 inch Palomar telescope? Rees11 (talk) 12:25, 26 July 2009 (UTC)

Anyhting built after WWII or anything built outside the USA is given in m. —Preceding unsigned comment added by 24.87.70.209 (talk) 23:07, 26 July 2009 (UTC)

Yes I know, but there was already a conversion to ft+in. I have changed it to inches. Rees11 (talk) 23:44, 26 July 2009 (UTC)

Too much weight on University of Florida

Too much of the contents of this article is about the Univ. of Florida. The article itself admits the Univ Of Florida owns only 5% share of the project, has an investment of a mere US$5 million, and that it gets to use it just 20/365 nights (5.5% of nights) per year. This article could be improved if this inbalance was addressed. —Preceding unsigned comment added by Rob99324 (talk • contribs) 14:57, 26 July 2009 (UTC)

Single mirror?

Not an expert here: does single mirror really mean one, single cast reflector? If so, how does this telescope's primary, composed of 36 hexagonal mirrors, compare to Palomar's honking big, one mirror? The citation is from MSNBC, not Sky & Telescope so I have to ask. --CompRhetoric (talk) 16:15, 26 July 2009 (UTC)

It is clear case of bias to exclude the largest telescope in the world and make some news. The largest is Large Binocular Telescope (1.4 meters larger than GTC when LBT is in its monocular mode). Being first in some obscure way just sounds better than being second in clear count. 217.18.135.36 (talk) 15:03, 27 July 2009 (UTC)

When most astronomers refer to a segmented mirror, they still speak of it as a single entity, or mirror. Therefore I'm changing the "world's largest single optical telescope", which just sounds weird, back to "single-mirror". The reason I originally made that edit was to be clear that the LBT is the largest optical telescope and has two mirrors. If the GTC or HET or one of these segmented ones were larger than the LBT's two mirrors, then leaving out "single-mirror" would be appropriate.

I can't quite make out what the comment above was getting at, but this distinction has nothing to do with comparisons to single-cast, monolithic mirrors, but rather the LBT for the reasons stated above. Hope this makes sense. General Epitaph (talk) 07:16, 8 September 2009 (UTC)

I just spoke with some more astronomers, and they disagree with my assessment. I can't think of a good way to word it. Its the largest single-aperture, or single-primary objective, telescope. The key is to point out that it's not 2 giant mirrors like the LBT, but the user who edited it was correct, "single-mirror" would not be appropriate.

I am going to put "single-aperture", if someone else can think of a better way to distinguish it from the LBT I welcome the edit. Cheers, General Epitaph (talk) 18:40, 10 September 2009 (UTC)
