Qualified - 3 Points

1) Focus/Sharpness - Focus is good
2) Composition - Perfect.
3) Star Quality - Stars are oblong on, especially on the right side. Likely caused by an optical path alignment problem, such as the camera not being square to the focus tube?
4) Processing Skills - The Black point is good. Stars are a bit too crunchy from over-sharpening.
5) Exposure/Depth - Good
6) Technical Bonus - n/a

Well done - this is a pleasing image of the Hercules Cluster. Only the oblong stars and slight over-sharpening separate this from being a superb image.
