M45 ‘Pleiades’

I took this image of the Messier 45 ‘Pleiades’ back on the 6th of December 2013 but only recently got around to processing the data.  Processing this was a little challenging, particularly given that I did not take any dark frames or flats to reduce the noise and dust motes that are now visible in my optical train.
