The conditions were just amazing, so I didn&#8217;t have any problems to see the comet and capture it in the center stage among lot of deep-sky objects around (like <em>California nebula<\/em> or the structures of dark nebulae in faint northern Milky way). The first image shows view around the La Silla <a href=\"http:\/\/www.eso.org\/public\/teles-instr\/lasilla\/swedish\/\" target=\"_blank\">Submillimetre telescope<\/a> (with the dome of 3,6-m telescope in the distance). Comet is just up on the left part of the view. Bright object close to the plate is planet <em>Jupiter<\/em>. In the reflection you can also recognize the Milky way constellation <em>Southern Cross<\/em> and famous star <em>Alpha Centauri<\/em>. And also you can try to find the <em>Dark coalsack<\/em> nebula or <em>Carina nebula<\/em>. Green hue is caused by airglow.
