Description

So far I've been rather dissatisfied with my "version" of the globular cluster Messier 13 because it lacks brilliance and depth. In the end, this is unfortunately due to the missing Astronomical Night.

But now, in issue 34 of the German magazine "astronomie", I came across a special feature of M 13 that I had not known before. Now I can't get the structure out of my head looking at the photo...

This is an area of lower stellar concentration or offshore dust clouds forming the shape of a three-bladed propeller.
