Bernd, The ISO was set at 200. I don't use the *istD on automatic ISO. When working with a tripod it doesn't make sense either....:-)
The reason you see noise is that the noise reduction was turned off. Normally I have it turned on, but after loosing quite a lot of nice bolts of lightning during the dark-frame exposures, I decided I would like to try without and see how it turned out. And truly, the colour noise was quite awful at 30 seconds exposure. In this PESO, I reduced noise with NeatImage (boy do I like that program). Still, the result is not as good as with noise-reduction on. It is a bit time-consuming (understatement) to use NeatImage on each and every shot too. I'm pondering whether it's possible to take one shot with the lens cap on and use that for dark-frame exposures to be added to the shots later.
