Largest Radio Telescope in the southern hemisphere[edit]

Tidbinbilla is the largest antenna in the southern hemisphere, but it is a communications station not a radio telescope. Parkes is the largest radio telescope. --Robminchin 04:22, 22 October 2006 (UTC)[reply]

Actually Parkes is the largest steerable dish used for radio astronomy, not the largest radiotelescope. The Molonglo Observatory Synthesis Telescope is larger (but is not a dish). I'll reword slightly. -dmmaus 06:48, 22 October 2006 (UTC)[reply]

Tidbinbilla can also be used as a radio astronomy antenna. In fact, both Parkes and Tidbinbilla have done both. --Spindocbob 08:46, 23 October 2006 (UTC)[reply]

Huh?[edit]

The intro says

"It is best known as the dish which sent images of the first moon landing to the rest of the world."

But the section headed Apollo 11 Broadcast says

"Parkes Observatory was not the first station to broadcast images from the Apollo 11 moon landing"

Seems a bit fuzzy to me, misleading at best. Should the intro say it is best known as "one of the" dishes which sent images to the world? Kaiwhakahaere (talk) 20:45, 28 February 2008 (UTC)[reply]

Goldstone was actually first, but the pictures were terrible. Honeysuckle Creek did the first ten minutes and Parkes the remainder. See: http://members.pcug.org.au/~mdinn/TheDish/ Spindocbob (talk) 12:22, 21 March 2008 (UTC)[reply]

Correct, the parkes relayed section is of much greater quality than the "one giant leap.." section of the broadcast.

confusing[edit]

The third paragraph under "The radio telescope" heading it says "It was used as a transmit uplink antenna in the Apollo program and has been abandoned since the early 1980s." -- Its unclear to me whether that means the telescope itself has been abandoned or the program this paragraph references —Preceding unsigned comment added by 61.68.22.48 (talk) 22:01, 30 August 2009 (UTC)[reply]

they're talking about the smaller dish. 121.45.165.89 (talk) 03:44, 21 October 2022 (UTC)[reply]

Better google doodle reference[edit]

When google add it to their logos page (http://www.google.com/logos/) please someone change the existing reference. It currently feels like a covert spam link (Whatever the MW shortcut for that is). kgoetz (talk) 09:47, 31 October 2011 (UTC)[reply]

Thanks to annon who fixed that up :) kgoetz (talk) 22:27, 31 October 2011 (UTC)[reply]

Diameter[edit]

There is written: 'Upgrade to 64m from previously smaller aperture.' How large was the smaller aperture? Hobbema (talk) 10:25, 4 May 2020 (UTC)[reply]

Removed it. Claim is unverified and this source says the dish has been 64m from the start. Fountains of Bryn Mawr (talk) 01:45, 5 May 2020 (UTC)[reply]

National Heritage listing[edit]

I'm not sure the best place to add this information to the article so am posting a link here. In August 2020 the CSIRO Parkes Radio Telescope has been added to Australia's National Heritage List.

"along with two smaller radio telescopes."[edit]

This has no citation and I believe it is incorrect.

I am not editing the main page, as I might be wrong, but I want to draw attention to this.

You can see the eorror also in the sidebar, where two telescopes are listed, and then there is a third entry, which has no diameter (because, I suggest it does not exist). The confusion is probably because the second antennae is not used. "The parkes radio telescope" just refers to the main antennae, or perhaps the entire facility. 121.45.165.89 (talk) 03:48, 21 October 2022 (UTC)[reply]

I've been informed, anecdotally, that there is a third telescope, a small demonstrator for some "pre square kilometer array" technology, but I can't find anything written on it. 121.45.165.89 (talk) 03:57, 21 October 2022 (UTC)[reply]
