Description

M13, nothing special. Just to complete Messier series .

On star clusters I still have to learn, how to capture and process them.
The problem is the high dynamic range of these objects.
At the moment I capture them at min. exposure time (avoid over-exposure of the core)
But at the cost of the dimmer outer stars.

B, final) added some data to get it a bit more crisp
