Im guessing there is more than one category for this competition. It would be really unfair to be comparing images like the first 3 in the OP that are artists impressions made from numerical data against the time-laps pics that used real optics.
Description The Horsehead Nebula (IC434).jpg
English: This colour picture was made by combining several exposures with a 2048x2048 CCD detector at the 0.9m telescope of the Kitt Peak National Observatory. Observing conditions were not ideal throughout, and so only a select few of the original observations were used. The final tally used five frames in the B (blue) filter for a total of 22 minutes, three frames with the V (green) filter, 15 minutes, and two with the R (red), total 10 minutes. Each frame was carefully cleaned, a particularly difficult task for the blue filter due to internal reflection problems in the telescope, and then aligned and combined by computer to create this (approximately) true colour picture. The pixel size on the sky is 0.68 arc seconds; after combination, the final size is 1480x1366, or about 17x15 arc minutes. Orientation of thumbnail image: N to the left, E down.
