Description:
I've already sketched this object about four years ago, actually it was one of my first sketches. That time the sky was great, but this time I decided to put it on paper when the conditions were definitely poor. The idea behind was to simulate the night sky conditions when I last saw this object earlier this year from Budapest, our highly light-polluted capitol. So the sketch was done with a full Moon and light clouds all over the sky. SQM reading: 15.98m/arcsec2, 3°C. Dedicated to my friend Györgyi, she knows why. ;)
