Still noise with tripod

[Dave303]

I took a photo of the moon at night with a tripod. I set my ISO to 100 and my shutter to 5 seconds or so. The light intensity was to much of course but the sky was okay.

But despite the fact that I did use a tripod and set the ISO to 100 I did got a lot of noise. I didn't expect that and it shooke my world.

I have a Nikon D200 and used the Nikkor Zoom lens AF-S DX VR 18-200mm f/3.5-5.6G.

Is this because of the f3.5?

Thanks.

Can you post an example?

5 seconds falls under the "long exposure" range, so you may be getting noise from the length of the exposure.

The noise was in the dark sky areas? It's probably due to the exposure length.

Dear
The cause of excessive light in the picture is the duration of exposure
Or bad weather
We hope to see an example of the image to try to find out why

[i speak in math]

why is this in the lighting section?

in addition to the long exposure noise and amp glow...

You're also looking at underexposed skies, with blues - anytime you have underexposure, you're likely to see noise - especially in the shadows - even at iso 100.

Here is the link of the photo:

You can clearly see the grain or noise in de top left corner. Can this also be a result of the moving clouds? And I also understand the fact that the moon is overexposed, but that is an other case.

Five seconds seems like an awfully long exposure for your setup. While it may be night time here on planet earth, it is daylight on the moon, which is what you are trying to get a picture of. I would expect an exposure a bit closer to a daylight shot. Also, you need to keep in mind the "Rule of 600." This rule states that if you want to keep stellar motion from showing up in your images you need to divide 600 by the focal length of your lens to get the maximum exposure without movement. In your case, if you have your lens at its maximum 200mm, then the longest exposure you could have without seeing movement would be 3 seconds. Personally, I suspect the ideal exposure will be even shorter than that.
