alan4908 Posted April 23, 2018 Share Posted April 23, 2018 An LRGB image of two spiral galaxies that have collided and are now moving apart. Whilst the devastation of the impact was immense, you can still see a faint spiral structure in the smaller (NGC4485) galaxy. The larger galaxy (NGC4490), which is also known as the Cocoon galaxy, also shows a large Ha region. Collision debris can also be seen between the two galaxies. The image represents about 12 hours integration time and was taken with a SW Esprit 150 and a Trius 814 camera and was previously posted in the Deep Sky imaging section. Alan LIGHTS: L:13, R:19, G:20, B:21 x 600s, BIAS:100, DARKS:30, FLATS:40 all at -20C. Link to comment Share on other sites More sharing options...
