Qualifed - 3 points

1) Focus/Sharpness - Just a tad soft...could be seeing, but looks like we missed focus just a little to me
2) Composition - OK, would like to see the target framed just a bit farther to the right
3) Star Quality - Star shapes are good, but color is weak.
4) Processing Skills - Color channels are a little out of balance (red is shifted to the right) and image is dim overall - not sure what is happening to your color, it should be much stronger & you shouldn't need any false color. The histogram shows a lot of funny spikes?
5) Exposure/Depth - I would have expected a much brighter image with the Pro-II and this many subs (but you didn't say what exposure length you used?)
6) Technical Bonus - Yes - Ha+RGB
