Good effort Col.:thumbsup:
I think you may need to work on your tracking/guiding as your stars are somewhat elongated. This unfortunately has reduced the resolution of M13. The cluster resolves quite well based on your exposure combination. You could possibly stretch the data a little more to bring out some of the fainter stars, but be careful not to burn out the core.
