Overhead

We’re very lucky to live under the flight path of hundreds of geese as they fly from their resting grounds to their feeding grounds. We often hear them before we see them. The extra gives a better impression of the numbers involved.
I’ve noticed that there have been a number of “spots” on some of my photos and came to the conclusion that the sensor is needing cleaning.
But how!
A trip to a camera expert?
Or consult YouTube?
Eventually, I found I had to set the camera to manual so that I could get the mirror thing lifted so that I could clean the sensor.
It seems to have worked.
P.S. not blue skies all day. Some heavy rain and even a little hail!
