With one hour and twenty minutes of exposure and several hours of processing, I have finished my work on the Pleiades Star Cluster. Also known as the seven sisters, its stars are surrounded by blue nebulae, which are difficult to see in a telescope but easily visible through long exposure photography. As the blue stars move through these dust clouds, their light reflects off of them creating the nebulosity in this image. I am really pleased with the faint details of the clouds and their complex structure.
