Unsuccessful day!

It was very cold, very wet and very windy this morning, so I did not venture out. One thing I did plan to try though was using the bigger stopper on the fast-moving clouds. Sadly, by the time the rain stopped and I ventured out to try this, the wind had dropped, and the clouds were not moving much at all. Worse was to follow, as all the photos I took, of this and other subjects, turned out to be afflicted in the same way as the one above when I came to process them this evening. I think I have removed the offending object now, although I could not actually see it on the sensor.
