Very nice sketch of M 30. I have always enjoyed the string of stars on this one like "legs".
It's a beauty.

Yes, those "legs" were the first thing that struck me, together with its awkward structure. Definitely a favourite!

Isn't it interesting, that so many GC's display arm-like features? Do you think that is a result of some (rotating) gravitational waves like the arms of spiral galaxies? Or, did they ever measure any rotation around their cg's in GC's at all?
* cg = center of gravity

Regarding your question about the "arms" of globulars, Ferenc, I'll have to leave that for the experts because cosmology is not really my cup of tea...

Do you know what is the ligth pollution color at your observing site ? Do you ever get an SQM reading ? I'm curious to know.
