Twilight skies

For the last few weeks I have been trying to get out and capture the twilight sky, when it is that fabulous dark blue. Unfortunately it only lasts for about 30 minutes and I always seem to be busy at that time. But tonight i finally got it. I am so pleased with these. I ran them through Neat image to decrease the noise, cropped the second one and cloned out a few weird pixels, but otherwise they are SOOC. The settings were iso 200, f 7.1, ss 20 secs. You can see some chromatic aberration (the purple) around some of the lights, but I'm still happy. I used my 50mm lens - it was on the camera and I was too lazy to change.
