200: 1539:) mistakenly give the Keyhole the identifier NGC 3324. Our article repeats this, using APOD as a reference. But the catalogue uses the number 3324 for an emission/reflection nebula to the NW of the main Carina Nebula (roughly at epoch 2000.0 coords 10h 37m 20s, −58d 38m), as reflected by Simbad, the NGC Project website, and the Night Sky Observer's Guide (Kepple et al.). So far as I know, the Keyhole itself does not have its own NGC number. Is there another identifier for it? 332: 2507: 260: 233: 1618: 191: 270: 1396:
the objects history. It is clear their is bias here, because the article never has little written about the history or the discovery of this nebula. "Reasonable English" has nothing to do with the name of the Eta Carinae Nebula, whose supposition is only based on the the name "Orion Nebula", hence, this must apply to the dubious "Carina Nebula."
1324:" This pattern is repeated in the half-a-dozen other AAO images linked; and (I suggest) represents the most up-to-date usage, referring to the object as a whole as the "Carina Nebula" or "Great Carina Nebula", and reserving the term "Eta Carina Nebula" to the nebulosity around, and directly related to, the star itself. 471:
observers know it as the Eta Carina Nebulae, and it distinguishes it from several other known Carina Nebulae. Whoever requested this move, should be censured because it is not known as this by southern observers. (Note: There are moves afoot to eliminate this naming debacles, like this one, via the IAU.)

In older usage (see Burnham, e.g.,) the name "Keyhole Nebula" applies to all of NGC 3372 -- i.e., this is "the nebula that contains the Keyhole". Most modern sources I've seen use "Keyhole Nebula" just for the Keyhole itself. We probably ought to point out this divergence of names in the section on
1175:
Why argue with this person, when the entire article argues just one point of view? My question is why it is originally called the "Eta Argus Nebula", when at the time is was observed and orginally catalogue it was a bright star surrounded by nebulosity. All that was observed was a bright reddish star
388:
While it's amusing that you consider NED and Simbad gods of naming conventions (heck, why not?), I don't get those same results. A search for the "Eta Carinae Nebula" or the "Eta Carina Nebula" turns up nothing. Of course, under NGC 3772, the names listed include Eta Car Nebula, but not Eta Carinae
1481:
My criticism of what you added was not that I am disputing the validity of your name for the Nebula (though I dispute the primacy of it) I questioned what you added for its tone (being Pointy, POV and having undue weight for the intrioduction) and suggested a naming section as an alternative. I also

To quote Webb's "Great Diffused branching milky way nebula with interior darkness about η Argus", showing eta was essential to the nebula." or T.J.J.J. See's "Micrometrical measures of double stars in the great nebulae and cluster around &eta Carinae.." (1897), shows the importance of the nebula
2428:
Since the nebula is about 7500 ly away, the explosion must have occurred over 7500 years ago; but it was observed on Earth in 1841, so the initial light from the explosion reached us only 176 years ago. Thus from the explosion to the state we see it in now is only a span of 176 years, limiting the

Agreed that Eta Car is certainly a huge mess currently as well. Unfortunately, it seems that the actually important astronomical object articles here don't get any attention compared to those unimportant minor planet and exoplanet articles, and I'm already swamped on-wiki. I'll try to get around to
1395:
Thank you for showing your bias, as it is precisely my point. The name of the Eta Carina Nebula is based on precedence, not some airy fairy idea of modernity. If you knew anything about astronomy, you would realise that names are often highly dubious, whose order is often based or the discoverer or
1260:
No one is arguing whether eta Car is an important feature of the nebula: it is so, and has always been so. We are trying to find what the nebula is commonly called today. The list above is not an argument, but a listing of examples in an attempt to adumbrate which names are in common use. I did

I agree that diameter would typically imply a spherical object which could cause some confusion here. Perhaps some clarification is needed on where how this diameter was determined and what it refers to (e.g. largest, smallest, or average diameter). Also, a citation should be added for this value.
512:
There is absolutely no evidence it is just called the "Carina Nebula". As I said, when the star was 1st magnitude, it was hard to see the nebula, and the name Eta Carina Nebula was adopted. I.e. The nebula around the star.Thousands of southern observers called it the Eta Carina Nebula, and I have
413:
I agree with you, Keflavitch. This is more commonly known as the Carina nebula; I was very surprised at the redirect. The title Eta Carinae Nebula would be more suited to the ejections of the star Eta Carinae itself, aka the Homonculus. The most obvious reason for this is that the Carina nebula is

and named by him "King George's Star", yet universally known now as Uranus (and of which the pronunciation has changed radically over the past thirty years). As for this object, "Eta Carina Nebula" is as familiar to me as it seems to be to you, but I am at least open to the possibility that it is
1401:
If you examine SIMBAD, you will find that BOTH names are listed, and if you understood the history, "Eta Carina Nebula" come before the name "Carina Nebula." As an visual observer since 1973, I have always known this as the "Eta Carina Nebula", and most in the southern hemisphere know it as such.
429:
Carina Nebula is not just the more accurate name, it's the most common name. A Google image search for "Carina Nebula" brings photographs of this larger nebula, and a search for "Eta Carinae" brings up images of the star itself and the homunculus. For these reasons I am submitting this article to

You statement, "but what it is commonly called now", is clearly opinion than based on fact. Naming of astronomical objects is fraught will people trying to make a name for themselves, or imposing their will over historical precedence. Foolishness to claim otherwise shows either naivety or bias;

470:
Keflavich is 110% correct, and the other statements here are silly and irrelevant. It is called the Eta Carinae Nebula, because when it was observed in the 18th Century, the star of Eta Carinae predominated the nebula because of its brightness, in fact, making the nebulae difficult to see. Most

Knowledge is supposed to be "on good faith", but your response here is that you have no intention of doing so. So you want consensus via unveiled threats, well all it shows is you've already lost the argument. I will not back down on this imperialistic attitude. Facts speak stronger than mere
1279:"Why argue with this person, when the entire article argues just one point of view?" Mate, the POV you want to detect in the article is not mine: my sole contribution to this article was a reference to the Caldwell catalogue -- a minor point and not the principal one of this discussion. 2445:
I've reworded the paragraph I think you're having trouble with. Hopefully it is clearer and addresses any confusion. The largest distance of the outer shell of the bipolar nebula from the central object is 22,000 AU, about a tenth of a parsec. I think I'll add that too, good information.

The nebula is not called the Eta Carinae nebula, it is the Carina Nebula or the Great Nebula in Carina. The Eta Carinae nebula is also known as the Homonculus and is the much smaller nebula surrounding the star.

Third, additions should be in reasonable English and make reasonable sense; is this an argument for Eta Argus as a title? Or that southern observers should take precedence because it's in the the southern sky?.
