The following image of the Heart Nebula was acquired by Adrian Brown over several nights during August, September, October and November 2007. To cover the whole nebula Adrian needed to shoot a 9 panel mosaic with his 80ED refractor and ATK16HR CCD camera. The image is comprised of 64 x 30 minute exposures distributed over 9 panels. The equipment used was an Astronomik 6nm Hydrogen-Alpha filter, ATIK ATK16HR camera, Skywatcher 80ED Pro refractor, Celestron CGE EQ Mount, Skywatcher 80T guidescope, and an ATIK ATK-2HS guide camera. The raw images were aligned and stacked in Maxim DL 4.53, the mosaic panels aligned in Registar 1.0 and the mosaic assembled in Maxim DL 4.53 and processed in Photoshop CS2. There are lots of interesting features to see in this image. Can you find the little planetary nebula WeBo 1? (hint - look along the left hand edge of the image).   ...back to lo res image.
