Content of this article edit
According to the celestial longitude article, celestial longitude can be the longitudinal coordinate of any celestial coordinate system. However, all literature I have read says that celestial longitude is the same as (or another name for) ecliptic longitude. Shall this be corrected in the celestial longitude article, for example by redirecting it to ecliptic longitude or ecliptic coordinate system? Iceblock (talk) 19:39, 10 November 2016 (UTC)
- No references and the term isn't mentioned in the linked article on celestial coordinate systems. I say wipe it, and a redirect seems like a good replacement. See also Celestial latitude. Lithopsian (talk) 19:58, 10 November 2016 (UTC)
- This revision seems like somebody's OR. Unless sources can be found to confirm the claims in this article, it should be changed back into a redirect to right ascension. Praemonitus (talk) 20:00, 10 November 2016 (UTC)
- I think the original redirect to right ascension was incorrect. It was subsequently changed (and reverted and then changed again) to ecliptic longitude, give or take a double-redirect. I can't swear to that from personal knowledge or give references, but that's the gist of other Wikipedia articles and is the common usage in astronomical texts.

- Given a potential redirect goes right to Celestial coordinate system, which is what the original user wanted to direct people to anyway, I have re-instated the redirect pointing there (specifically to #Coordinate systems). Primefac (talk) 20:39, 10 November 2016 (UTC)

I disagree with the redirect to Celestial coordinate system and recommends a redirect to Ecliptic_coordinate_system#Spherical_coordinates instead. In the Ecliptic coordinate system article, "celestial longitude" and "celestial latitude" is mentioned. Iceblock (talk) 15:57, 11 November 2016 (UTC)
- I think celestial coordinate system is the better choice, since this is "celestial" longitude. If "celestial coordinate system" is redirected to Ecliptic coordinate system then that would be fine, but it isn't. Galactic coordinate system is a celestial coordinate system using latitude and longitude. So celestial latitude and celestial longitude should point to celestial coordinate system -- 65.94.171.217 (talk) 05:50, 12 November 2016 (UTC)
- Celestial coordinate system has one obvious problem as the redirect - it doesn't mention the term "celestial longitude". The article ecliptic longitude does explicitly mention celestial longitude as a synonym, but there may also be other articles that make that clear. Lithopsian (talk) 23:07, 12 November 2016 (UTC)
Celestial longitude is the same as Ecliptic longitude. See the entries at [1]. Tfr000 (talk) 13:56, 4 July 2017 (UTC)
