Equipment - 10" dobsonian on a tracking platform with Pentax xw 20mm eyepiece, giving a 60x magnification and 1.17° field of view.
The cluster was sketched during two nights on August 23/24 in a total of 5,5 hrs from my yellow zone in Almere (The Netherlands).
I used 4 black fine liners of different size on white paper and digitally polished some of the brighter stars while giving six others their red color.
This is the original (inverted) field sketch.
