Pacman nebula: my black and white (5 x 30 min with 30 cm newton @ F/3.9, ST-10XME, 3 nm H-alpha filter.) merged with the picture by Jim Thommes, a Californian amateur.
See his colourful picture at http://www.jthommes.com/Astro/NGC281.htm
Also the image processing is done by him. Both contributions benefited from the merger.
