I saw the central star in M57, using my 10-inch dob a couple of years ago at 300x. It was a great night from a really dark sky site in the mountains of western NC. Kind of hard to keep up with the nebula in the dob at that magnification but the central star was plainly visible. That was the night that I learned that my scope could reach mag. 15.6 at that magnification. The central star is approximately mag. 14.8 but it is not all that easy to see because it is located within the nebula. Being in the nebula reduces the contrast and makes it much harder to see, so you will need a good dark site (green zone or better) and good seeing (atmospheric steadiness) with very high power to make this observation.
