Astronomical Dusk Photo[edit]

Years ago, I posted a very simple chart that really had nothing to do with dusk. Last night, I set up a tripod with the intention of grabbing an actual dusk photo. Hard to do, because you'd eventually be taking a photo of nothing...lol. I kept clicking until there was nothing except artificial light coming over the Horizon from Los Angeles. I posted the last photo in the lot, where you can still see natural light. This is probably as close to an actual Astronomical dusk shot in high def we are going to be able to get. I added some saturation or we'd really be looking at the abyss here. So...if a consensus doesn't like it, take her down. It's not going to win any photo awards; there's hardly an image there, but I think it is what it is. Thanks Pocketthis (talk) 15:59, 19 June 2016 (UTC)[reply]

Also, I changed some text in the nautical twilight definition. It previously said that the horizon 'at that time' was no longer visible.

I wouldn't agree with that statement, even if we were talking about night time. The horizon is always visible at night. The stars are distant Suns that light the sky enough to see the horizon, even on a night with no moon. The only time the horizon disappears, is when the sky is completely covered with a blanket of clouds. Then no astronomical light is allowed to illuminate the sky. Even when it is so dark, that you can't see your hand in front of your face, the horizon can be distinguished from the sky. Pocketthis (talk) 19:51, 19 June 2016 (UTC)[reply]

I have been waiting for the right evening to get an exact dusk shot overlooking my town. I needed there to be a moon coming up behind me to enhance the mountains in front of me, as well as some mist to bounce of of the city lights. I also need some traffic at exactly the right moment to be streaking past in the background. Last night was the night. This shot is a long exposure (approx. 20 seconds). Thirty seconds later it was nightfall. This is as close as I am able to capture our article title, and still make the shot interesting enough to view. The previous shot was also on time, but a bit boring. P.S.: The wind was really blowing strong, and my tripod was truly being stressed, but overall, it was a moderate success. Any questions or objections: fire away.→ Pocketthis (talk) 16:32, 11 May 2017 (UTC)[reply]

Astronomical vs. Civil Dusk[edit]

Pocketthis, can you quote the source for these two sentences in the introduction? I can't find the source language on the web, and I don't have a physical copy of this dictionary.

Dusk occurs at the darkest stage of twilight, or at the very end of astronomical twilight just before night.

and

"Dusk" is actually short for Astronomical Dusk, or the darkest part of twilight before night begins.

My experience is that everyday usage of the word "dusk" refers to the end of civil twilight, or possibly the end of nautical twilight. I've never heard someone refer to it as the end of astrmonomical twilight, which could be an hour-and-a-half or more past sunset—well beyond the time when most would consider it to be dark. Generally, parks or playgrounds might say "closes at dusk", which means "dark". Google "dusk" and it gives the time for the end of civil twilight.

I'm just looking for a source, because I am skeptical of the way it is worded now. --TWCarlson (talk) 00:42, 21 August 2016 (UTC)[reply]

That's interesting, because I actually believed it was a period of time that started at the end of nautical twilight, and extended until nightfall. However, in making those corrections, I was reverted more than once by experienced Wikipedians I respect, that insisted it wasn't a "period of time", but rather an instant just before night. I didn't really understand their explanation, so I tried to educate myself on the issue with research. I didn't have to dig too deep, as the first two major dictionaries I checked online, both stated that Astronomical Dust (better known as Dusk) was the very end of twilight just before nightfall. That's how we ended up where we are. Also, the fact that every twilight related article had a different view on the definitions of the the three twilight periods, we decided to eliminate the conflicting info, and make all the articles jive. I hope I have answered your question. Thanks Pocketthis (talk) 02:16, 21 August 2016 (UTC)[reply]
