M13 is now at a good point, high up at night. A quick (very quick) look at this bauble.

Can you find the very small background galaxy in this image? It's at magnitude 18.

What are globular's exactly?

Very pretty tight agglomerations of many stars that are gravitationally
bound together and continue to get more tightly bound by flinging the
odd star out to infinity whilst the rest contract into towards the core.

M13 is a very bright example and easily found even by a novice star
hopper. Just down from eta Hercules about 1/3 the way to zeta.
