We've made so many advances in our understanding. A few centuries ago, the pioneer navigators learnt the size and shape of our Earth, and the layout of the continents. We are now just learning the dimensions and ingredients of our entire cosmoc, and can at last make some sense of our cosmic habitat.

My astronomy sketches. Hover mouse over image for the inverted look. For fainter objects, take a look at the black-on-white original, sometimes it reveals more details.

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. ;)
