Merveille du Monde
I took many similar images at different exposition, all around 20 seconds, at ISO 400, f/11 or f/16. I decided to try using image-stacking of 6 frames to remove noise without degrading the sharpness or losing details. This process removed the light streaks and diffraction stars from the cars (at the right of the picture) because they were different in all the frames, so I simply applied back that area from one of the source image.
The image-stacking noise removal turned very well, but I am also investigating the next step, known as super-resolution. Super-resolution uses the difference in aliasing of different pictures of the same scene to extract details beyond what was found in the source images. It's been used in astro-photography for quite some time, as well as for satellite imagery and by military and governmental agencies, but hasn't really made much splash in the consumer world yet. I'll update this description as I make progress on the subject.
Thanks to everyone else in the group for once more letting me sneak out on the desert so I could take these pictures. I means a lot to me. Thank you so much!
Picture slightly cropped, levels adjusted, and post-process using the methods described above.
*** Note: It reached Interestingness for 2008-08-18 on 2008-08-19, going all the way up to 30th position! Thanks everyone!
*** Update 2011-04-26: I uploaded a new version. It's more detailed thanks to the PhotoAcute 3.0 beta. The contrast is slightly lower compared to the previous version to give a more natural look.
*** Update 2013-03-26: Lowered contrast slightly again. Removed a sensor dust spot. I recommend that you view the original, as Flickr seems to introduce some banding in the sky.
