Description:
Tiny, faint globular cluster with four clearly separated stars on its Western side. However, I'm not sure whether they really do belong to the cluster, or they are just plain foreground stars. With averted vision several other stars can be resolved at its slightly brighter core: two of them can be seen clearly with this technique, while some others pop up here and then when the atmosphere calms down for some moments. The core, just like the globular itself is not really sphere-like, but rather looks a little bit like an onion, with the thinner part looking to the East.
