Talk:Norma (constellation)

Fact dispute
History section seems very confused: The section needs a total rewrite. ... said: Rursus ( m bork³ ) 18:55, 21 October 2009 (UTC)
 * 1) a Southern Triangle distinct from Triangulum Australe is elsewhere unknown,
 * 2) a "Quadrans Euclidis" seems like a mega-confusion, Norma was earlier named "Quadra Euclid e s", Euclides is the correct singular genitive form, a "Quadra" is a quadrate, a "Quadrans" is a quadrant, i.e. an astronomical instrument,
 * 3) what has that hypothetical "Southern Triangle" to do with this article?
 * 4) If someone invented that hypothetical "Southern Triangle", it wasn't Plancius, but possibly instead Andreas Corsalius, or possibly Amerigo Vespucci; the early globes of Hondius and Plancius circa 1593 proves nothing, since they filled the southern sky with incorrect and too vague star descriptions,
 * 5) Abbé De Lacaille invented Quadra Euclides in the middle of the 1750:ies,
 * 6) the section needs citations.
 * Norma on star tales support that the article's current confusion is a confusion propagated from Star Names: Their Lore and Meaning, which is not very reliable. Richard Hinckley Allen, who wrote it had severe eyesight limitations and relied on obsolete sources which languages he didn't understand very well. ... said: Rursus ( m bork³ ) 19:12, 21 October 2009 (UTC)
 * I've likewise have had troubles finding the alleged source of Monoceros being a Persian invention, according to Allen refering to Ideler, but I haven't yet found the clause where Ideler claims that the Einhorn is the second horse. Instead I believe that Allen have misread Ideler, and that Monoceros was invented by Petrus Plancius or some c:a 1550 cartographer, such as Kurt Vopel. ... said: Rursus ( m bork³ ) 19:18, 21 October 2009 (UTC)

Stars section has an apparent error ″approximately 2000 years old and 10,000 light-years away from Earth″. I'm sorry but the laws must be obeyed. A light source only 2000 years old is not yet "visible" from 10000 ly distant. A light source about 12000 years old would have been detectable for the past 2000 years from an object 10000 ly distant.

The Norma Cluster
The Norma cluster (Abell 3627) is actually (at least mostly) across the border in Triangulum Australe. -- Elphion (talk) 18:01, 14 June 2018 (UTC)
