The Power Of Long Exposure

The Power Of Long Exposure

I made this with my "good" camera, this shows one of the streets in Florida at night time in long exposure form. You can really see the light pollution!

How long was the exposure ? I assume you had the aperture wide open or at least f/4 or even f/2.8.

I think 2.8, 15 seconds.
Long exposures make night look like day.

I've tried this some time ago, should try again this summer. I have a lens that opens to f/1.4 (I think) so it should give good results, or at least I hope...

Checked and it only opens to f/1.8 but that's still good. Some lenses can open to f/1.0 but $$$$$$$.

The other thing you have to do is have a really steady tripod, or your photo will be a blurry mess.

Yes, a tripod and the self-timer (or a remote release which I don't have), otherwise very muddy pictures.

I have a remote release, but I didn't use it for this photo. I just hit the shutter button and ran.
The streets would look a lot more dreary if I took the photo on the streets with just LED streetlights.

You can see an astronomical body in the picture, possibly Juipiter, Sirius or Mars. Which direction were you facing and what time of day did you take the picture?

O.K. Location, Florida, Direction...Looking West at about Midnight, roughly June 2016...what you are seeing is Virgo low on the Horizon, Libra a bit higher up and Scorpio a bit further up again. At the moment...and all those constellations are also visible here in Hobart...(and the ecliptic [that is the "rough" plane all the planets orbit the sun in viewed edge on, so appears as a line across the sky that all the plants, sun and moon move along])passes through them all of there and there are three bright plants there at the moment, (June 2016) but they are all slowly moving along the ecliptic so their positions relative to the stars of the constellations far behind (which don't move relative to each other...least not by any noticeable amount in a human lifetime) slowly change week by week.
From Florida at midnight Jupiter would be the lowest one, it is in front of Libra or Virgo, further up you will see Mars, it is about as bright as Jupiter or maybe slightly less and is in opposition to the sun...i.e on roughly the opposite side of the sky to the sun... so both Jupiter and Mars appear "full" like the moon but a lot further away...still, at opposition, they are "behind" us , close to us as they can get (i.e we are all on the same side of the sun, none of them is far away round the other side of the sun on the opposite side of its orbit) ....Mars looks a lot redder and will be the next brightest thing there. It is in front of the front end of Scorpio...i.e. the "pinchers" end which faces the border with Libra. Further back in Scorpio, higher up still in the sky is Saturn...it is a lot dimmer...because it is a hell of a lot further away. It has a "sandy yellowish" sort of look and is further back in Scorpio, near the stinger tipped tail which is marked by the star Shaula, or Lambda Scorpii to give its Bayer designation and it little apparent companion star...just line of sight...the two are actually very far apart ..this "double" marks the "Stinger" of Scorpio.
Scorpio's alpha star, the brightest star in Scorpio when Bayer listed them all about 200 years ago, is a Red Supergiant about 400 light years away....it, like Mars, looks red and will be there in the feild too...its name means "Rival of Mars"...but not when Mars is at opposition!
So the thing in your picture is Jupiter! Well caught!

I see a second object too...just to the right of the cables....maybe this is Mars and it has "gotten in front"....I'll go and have a look tonight from here and see where Mars has gotten to since I last looked about a week ago....its been rainy, cold and cloudy here for most of the last week so I havn't seem 'em recently!

Woah!, lookes totally bleached!, good photo though, it also shows the problem with post top street lanterns, sure they look nice, but they tend to throw light everywhere!

Wow, thanks for the analysis! I would maybe take a better photo if there were not so many trees in Florida.

You just need to find an open spot, away from the trees and lights. Oh, I "cheated" and used "Celestia" which runs on my other machine! I can't see those planets tonight, it has clouded over.

That's going to be hard to do, Florida is a tree city.
Update: I looked at the photo, and the little planet to the right of the wires is actually mostly the end of the cable, with a even tinier planet to the left of it. You have to look really closely.

The end of a piece of wire is very close to it and there is a reflection of it.

Just went out and had a geek at those planets as it is crystal clear this evening (29th June 2016)...they have moved quite a bit in the last two weeks.
The have all moved west, (closer to the western horizon when positioned at a given time and then compared to the same time the following evenings).

Jupiter has moved HEAPS...it has crossed Virgo and is now in Leo...way out in front. Mars has moved forward too, away from Antares and looks like it is straddling the border of Scorpio and Libra. Saturn has moved up a bot too, away from the "stinger" end of Scorpio up to sort of where Mars was before, near Antares. The gaps between all three have opened quite a lot wider than they were before.

I know the sun is coming the other way up the ecliptic...it appears to move east across the sky (when shapshot at the same siderial time each day) as we orbit it. In mid July it will be in Leo....because this is my "star sign" and my birthday is in late July...so Jupiter will be the first to pass into superior congunction...."behind the sun" round the far side of its orbit...as it gets closer over the next few weeks it will eventually go so far west it will disappear into the evening twilight as the sun comes the other way.

Looks like they use 1kw HPS post tops on their streets...

I'd go for a small aperture like f8 with a long exposure to get a good sharp & wide depth of field if I was using a tripod. f1.2 is useful for hand held shots but you get bugger all depth of field

I heard that f11 is the best for clarity.
I think they are more like 400 Watts, or even 250.

f11 gives good depth of field but any smaller and you start loosing sharpness. Depends on the lens but I personally normally don't go smaller than f8.

The problem with the smaller ones is you need a longer exposure, which creates a high chance of something going wrong.

250 or 400W HPS is very high for a post top. The most they'd likely be is 150W HPS.

They looked brighter than that, but maybe I have never seen a 150 Watt HPS on. I saw one of these without covers, and it looked like a bulbous 250 or 400 watt HPS.

I'm not doubting you, but 250w seems very high for a post top, especially on a residential street. Post tops all have plastic lenses so 250W or 400W HPS would probably melt the refractor.

One of my earliest photos was of these, but it only had the first style, there's a second one which is more pointier.

Ok those are made in 250W (that's the highest). Seems high for a residential street unless this is in a sketchy part of town. Doesn't look like it though.
