When I sent you my first Sombrero sketch, in December 2010, I promised to sketch it from a darker place to see the difference, so that’s it. If you search for the sketch called Happy Ending (M104 The Sombrero Galaxy) you’ll be able to see the huge difference between downtown and a dark place. Past July was a great month for me, I was allowed to observe many objects, including this amazing M 104. It was the first time I’ve seen it so bright and so detailed. Sombrero was 34º above the horizon, right toward the West. With direct vision only the nucleous was visible, however under averted vision the galaxy showed all its spell, as shown in the sketch. I hope you enjoy it, it has already become one of my favorite sketches.
Best regards, and clear sky to everyone!
