The camera was a D200 with Nikkor 20mm f2.8 1/8Sec @ f4.5, ISO 200.
I roughly followed the tutorial in the astro photography video, with the exception of masking the foreground.
I'm not confident there was NO movement between exposures, so I asked Ps to align the layers. Not sure that was a good idea but will try again without aligning layers when I get home.
The first image was exposure 10 of 10, clearly showing cars and headlights in the scene, all bar one exposure had cars visible on the road.
The second image is after the median layer blend, all the cars removed and to my eyes it seems smoother, noise wise, although not really very sharp.
Finally a 100% crop in Ps which shows the lack of sharpness and chromatic aberrations at the junction of the road and wall. There is also a fringe on all of the images at the skyline. This may be mirror slap because I didn't take that much care with my exposures, this really only being a quick experiment.
I will post some more results when I have processed the other images at home.
