Comment :

This series of photos I started earlier relative what I normally do. At this time of the year it isn't dark enough until one hour later. If you look closer to the full resolution image you can see a lot of stains left from the cleaning, this time I didn't do anything to reduce them. Maybe look terrible but much better than normal.
