Talk:Deep-sky object

message: "Since surface brightness is invariant to distance" - could use some explanation. I think what this means is that an object that's further away covers less sky and also appears dimmer, so these effects cancel out.  —Preceding unsigned comment added by 76.126.208.164 (talk) 04:11, 1 November 2009 (UTC)
thread_title:  Invariant to distance 

message: Article was rearranged and edited for content and logical definition. Looking through the reference we have to base this article on I have come up with these definition parameters:
*Deep sky objects are visual objects, you have to be able to see them.
*Deep sky object is a post 1940 term limited to the amateur astronomical realm.
*Deep sky objects are non-solar system non-stellar objects.
*Deep sky object is a visual, not a technical term (any non-single star object can be a Deep sky object). Also, parts of structures are Deep sky objects.
*Many extra solar system non-single stellar objects are not Deep sky objects such as the Milky Way, dark matter, structures in the radio and high energy realm (i.e. if you can't see it in the field of an amateur telescope it is not a Deep sky object).
Cleanup also per:
*Cleaned up some redundancy with other articles.
*WP:DICTIONARY and WP:V - def did not match references and "phrasings such as "is a term for"" is not encyclopedic.
*WP:NOTDIRECTORY and WP:EL - cleaned up directory of loseley related material or external links. Links deleted in deference to directory link.
*WP:NOTHOWTO - cleaned up for allot of advice and how-to links.
*DSO's are a post 1930s-40s general concept so they do not have the specific history described in the "History" section, that material is relevant to what it describes (galaxies, nebula, etc).
*Messier and New General Catalogue are not catalogs of DSO's since DSO is an informal term and they predate that term. Uppsala General Catalogue is a catalogue of galaxies.
*subbed a more descriptive image. ESO 510-G13 is a very pretty image but it belongs at Galaxy.

thread_title: Re-write

message: It seems that both spellings are good, "deep-sky object" and "deep sky object", but they are interechangeably used within the article, which is not quite along the guidelines of Wikipedia. We should adopt only ONE spelling, and mention the variant in the intro, and stick to the first one for the rest of the article.
However, I do not make the change myself, as I wonder whether or not we should hyphenate. English is not my first language, and while I'm pretty good in Shakespeare's language, I would not pretend to be even near perfect... My understanding of English grammar is that it should be hyphenated, but maybe I am wrong...

*Support. Sure. This is a simple application of a widely supported principle for the use of a hyphen in a compound attributive modifier. See WP:HYPHEN, which is part of WP:MOS. Wikipedia, like any publisher (construing that term broadly) imposes its own preferred style for punctuation, rather than attempting to follow the wildly unreliable punctuation of "reliable sources", however reliable they are for their content or for their choices of terms. WP:TITLE has nothing to do with style choices, and is appropriately silent on the topic of punctuation. NoeticaTea? 02:19, 18 September 2011 (UTC)
thread_title: Survey

message: Hi there. I was told to ask on this page how the community feels about changing the redirect for Deep sky from this page to Deep Sky, the article that I created yesterday for the documentary. How do we feel? Osh33m (talk) 16:39, 23 April 2024 (UTC)
replies: text: This article would be the WP:PRIMARYTOPIC. The film uses this topic as a title. So the current redirect and hat seems correct as is per WP:AMBIGTERM---> primary topic article. Fountains of Bryn Mawr (talk) 21:03, 23 April 2024 (UTC)
