Talk:Corona Australis

Overall brightness

This constellation "has an overall brightness of 16.446" ... 16.446 what? I tried to find the units in the wikipedia article on stars, then did a google search but couldn't find anything. If you know the answer please fix it...

It probably has something to do with amount of radiation received from the stars in the constellation, divided by its surface angle: which says more about the constellation's small area, than about the brightness of the stars in it. I will remove the statement as it is misleading.

Contradiction

Look at the info boxes at the end. As Ptolemy had already listed both Sgr and CrA, how could Bayer have split Sgr to make CrA? B00P 05:47, 31 January 2006 (UTC)

Very good eyes of thine, B00P!! We'll deal with such problems in Astronomy/Constellations Task Force. Bayer didn't split Sgr to make CrA. Bayer did not change the sky at all, Sgr and CrA were separate all the time, and most other constellations allegedly split by Bayer, were in fact split by Tycho Brahe or Petrus Plancius.

The article is well written and sourced properly. Just few things before GA:

This is it for now. I'll have another look at the article once this issues are solved. Cheers! — TheSpecialUser ^(TSU) 06:52, 14 July 2012 (UTC)

Variable Stars

Shouldn't these be included in the "Stars" section instead of "Deep sky objects"? VirtualDave 02:49, 5 October 2012 (UTC) — Preceding unsigned comment added by VirtualDave (talk • contribs)

I felt the article read better with them listed in the molecular cloud in which they occur, rather than appended onto a huge list of stars. Casliber (talk · contribs) 05:20, 5 October 2012 (UTC)

Yeah, they're not particularly important stars except in the context of the cloud, as far as I know. If you think there's a better way to fit them into the Stars section, do mention it - I'm all ears and definitely open to options. :) Keilana|^{Parlez ici} 05:51, 5 October 2012 (UTC)

Understood. I was looking at it from the viewpoint of consistency with other articles on constellations that included variables in the "Stars" sections, but if you look at each article on it's own, then obviously you should do what works for each article. Great article BTW! VirtualDave 11:46, 5 October 2012 (UTC) — Preceding unsigned comment added by VirtualDave (talk • contribs)

Thanks-I'm usually one for consistency but the star bits are a challenge....see Bootes for a Work in Progress that is a major challenge.... :/ Casliber (talk · contribs) 14:35, 5 October 2012 (UTC)

I'm definitely one for consistency but there's always exceptions, I suppose. Bootes is a ridiculous organizational challenge - I'm still not sure where to go with that. Keilana|^{Parlez ici} 15:52, 5 October 2012 (UTC)

Change to the {{sfn}} template

G'day all, just wanted to mention that recent changes to the {{sfn}} template affect the way it displays in some instances where it is used with a full date, per fn 57, 58 and 78 of this article. As it is used in that way in this article, and there might be more than one editor of this article that has used the template in this way, I thought I'd mention here that the discussion is ongoing at Template talk:Sfn#Query re: loose ampersand using sfn and harvid.

Proposed image addition: NOIRLab annotated chart of Corona Australis

Hello, I am affiliated with NSF NOIRLab and I would like to propose an additive image contribution to this article for community review. I note this is a Featured Article and I fully respect its protected status — this proposal is offered for consideration only, and I am happy to withdraw it entirely if reviewers prefer the article as it currently stands.

To be explicit: this is an additive proposal. The existing naked-eye photograph (File:Constellation Corona Australis.jpg) would remain in place, untouched. The NOIRLab annotated image would be added immediately above it in the same section, so that readers see the wide-field photograph followed by the labeled reference chart.

• Proposed change: Add an annotated wide-field image of Corona Australis at the top of the "Features" section, directly above the existing naked-eye photograph.
• Image: File:Corona Australis (Annotated) (corona-australis-ann).tiff
• Suggested caption: The constellation Corona Australis showing the IAU boundaries, the constellation stick figure, and labels for its brightest stars. Astrophotograph by Eckhard Slawik, from NOIRLab's 88 Constellations project.
• Placement and layout: Layout with both images in the "Features" section. The annotated image would be placed as a left-aligned thumb immediately above the existing naked-eye image, which remains unchanged. The "Features" section is long and text-rich (covering stars, the molecular cloud, and deep-sky objects across multiple paragraphs and subsections), so two stacked thumbs at the top of the section sit comfortably alongside the surrounding prose without crowding the figures that appear later in the section.
• Justification: The two images serve different reader needs. The existing photograph conveys the visual impression of the constellation as seen by the naked eye, while the annotated chart lets readers identify the IAU boundary, the stick figure, and the named stars discussed throughout the "Stars" subsection (Alpha, Beta, Gamma, Epsilon, Eta, Kappa, Lambda, Zeta, Theta CrA). Having both adjacent makes the identification of the stars described in the text considerably easier for readers unfamiliar with the southern sky.
• License: CC BY 4.0 (NOIRLab/NSF/AURA; photograph by Eckhard Slawik).

Here is the exact wikitext for the proposed insertion in the "Features" section:

The constellation Corona Australis showing the IAU boundaries, the constellation stick figure, and labels for its brightest stars. Astrophotograph by Eckhard Slawik, from NOIRLab's 88 Constellations project.

The constellation Corona Australis as it can be seen by the naked eye

I welcome any feedback. Three fallbacks I would like to offer up front: (1) I am happy to adjust the caption wording in any way reviewers prefer, including shortening it or rephrasing the credit; (2) if reviewers prefer references over inline external links in captions, I can replace the direct link with a `<ref>` citation to the NOIRLab 88 Constellations page; (3) given this article's Featured status, I am entirely willing to withdraw the proposal if the community concludes the article is best left as it stands. Thank you for reviewing. Marcodatadev (talk) 00:51, 15 April 2026 (UTC)

Done I swear, these requests take me half an hour to do every time, not because they're difficult, but because they pull me down an astronomy rabbit hole every time 😂 DiscoursesonLivvy (talk · contribs) 03:17, 15 April 2026 (UTC)
