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 clos to the full resolution image you 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.

Comment : A close up into the galaxy. It needs a lot of more exposure, many hours. Partly because of massive light pollution.
