Sheep and sunset in the Brecon Beacons

Too much cloud. A long work day finishing at 6pm so I grabbed the camera and lenses and drove to Clyro. Another abortive attempt to see the Panstars Comet. Too much cloud. However the sunset was lovely and the snowy beacons were breathtaking. Unfortunately with the blank snowy skies and hills it has shown up what appears to be dust on my sensor. Cleaning it looks scary according to my google search. I will clean the lenses first I think.If it is still there I may brave the sensor cleaning. Bummer.
