It was the end of an astrophotography session, about 3:30 in the morning. I looked at Stellarium and found out that the huge globular cluster, the biggest we know of in this galaxy, with approximately 10 million stars, was out but low in my southern horizon. Decided then to take an hour and a half of one minute exposures just for fun, and this is the result: Omega Centauri from my rooftop!!!
