(Additional notes below)
I took the subs for this image of M45 Pleiades (The 7 Sisters) about a week ago. I am adding it here for completeness, but this doesn't really show the beauty of it. There are supposed to be trails of blue nebulosity winding around the stars. I am not sure what went wrong. I have to take another few hours of exposures and add to this to see if it improves.
