This sketch was a challenge. I’ve tried to interpret the proper relative brightness of the stars but the result lacks the real shine of the main ones.
This night was exceptionally clear, NELM was rather 4.7. I was experimenting with using black and blue pens for annotations and mixed up in the end.
