Messier 10
M10, or NGC6254, is a seventh magnitude globular cluster in the constellation Ophiuchus, close to M12. About 16,000 light-years away and about 70 light-years across, M10 on the sky has about half the diameter of the full moon.

M10 seems to be slightly brighter than M12, but in a 8-inch it is hard to resolve. At 56x, M10 shows up pretty nicely, but is still unresolved. The increased contrast of the higher magnification will make the cluster jump out at you. A 10-inch or larger will surely resolve this globular better.
