51-year old Christian Sasse is general manager of an electrical engineering company, an avid amateur astronomer and of course a chess player. He is the owner of three telescopes which form part of the Global Rent-a-Scope network, which is a system whereby amateur astronomers can rent time on telescopes in various places around the world. These telescopes can be controlled via the Internet and, after the images have been taken, they can be downloaded and processed by the user. Christian generously offered GMs John Nunn and Vishy Anand time on the GRAS telescopes.

John will present a chess puzzle to the audience. There’s a prize of a 290 free month plan on GRAS for a lucky winner, who will be chosen at random from the correct entries.
NGC 6334 – the "Cat's Paw Nebula", so named because it resembles a huge paw print in the heavens, islocated near the tip of the Scorpion' s tail in Scorpius in a massive star-forming region. It is about 5,500 light-years from our Solar System. John spent a long time getting a decent image of this. Quite a large object, about half a degree across. Very red. [Click to enlarge]
The Crescent Nebula (NGC 6888 in Cygnus) is a bubble about 25 light-years across carved by the powerful flow of material from the central Wolf-Rayet star. It’s about 5,000 light-years away. John says he likes this picture because the nebula contrasts nicely with the rich background starfield. [Click to enlarge]
Centaurus A (NGC 5128 in Centaurus) ia an elliptical galaxy about 11 million light-years away. It has a large dust lane across the middle, which is apparently the result of the elliptical digesting a smaller spiral galaxy which it has collided with. It has an active nucleus with strong radio and X-ray emissions. [Click to enlarge]
The Snake Nebula, also known as Barnard 72, a dark nebula in the Ophiuchus constellation, is a small S-shaped dust lane that snakes out in front of the Milky Way star clouds. About 650 light-years away. You can see another dark nebula to top right. [Click to enlarge]
