Pleiades (2017)

It has been a couple of years since I last imaged Pleiades (M45) which is surprising since it is my favorite open cluster especially because you can see it well with the naked eye.  This was taken over four nights.  I am happy with how it turned out overall but the star halos around the four largest stars were driving me crazy so I made a revision after tweaking them somewhat.
