In a clear night I recorded this image of “Messier 100” – a spiral galaxy located within the southern part of constellation Coma Berenices – from Los Llanos de Aridane on La Palma. It is an LRGB composite consisting of 11 luminance frames a 600 seconds and 9 red, green and blue frames a 150 seconds respectively. The image is also available in full resolution. The seeing conditions tonight were perfect (seeing ~1.95″) and there was no local wind. The annotated image shows a lot of other interesting objects like NGC4323, IC783, NGC4312 and NGC4328 beside M100. Some objects I was not able to assign, yet – those are marked with question marks and could be additional galaxies.
