Atop Swirl Howe

We returned to the Lake District today because Tony had left his glasses in a cafe. We thought we may as well spend the day there as drive straight back! According to a walker on Weatherlam, it has been hazy in the Lakes for a couple of weeks and today was no exception so blips did not do the view justice. The sky did not clear till we were back down in the Coppermines - par for the course.

Our route was Coniston - Weatherlam - Black Sail - Prison Band - Swirl Howe (tea stop) - Coniston Old Man - Coppermines track - Coniston. This is Tony admiring the view on top of Swirl Howe with Weatherlam in the background. My knees were a bit rough by the time we came down, but an ice cream soon did the trick.

Advice please, if you look at the blip on this link, you will see some spots on the sky in the top right hand corner. They are not on my lens as I clean them religiously. Could they be on the sensor? How would I find out and what should I do?
