Yes, I am still showing pics from my night at Gaviidae. My cold persists and if you look to the right and see the temperature here in Mill City, you will see why I’m staying inside.
I talked about Bokeh recently and this is another example of that effect. The subject in the foreground is a big star decoration and the glowing circles are from small Christmas lights in the background that are out of focus and causing the bokeh circles. You can see everything in focus in the wide angle photo. Another term for these glowing out of focus disks is The Circle of Confusion. The light coming through the lens is has not focused to a point yet by the time it hit the sensor and is thus “confused.”
You might be suffering from this on a regular basis with other aspects of your life. Now you have a great term to use to describe it. 
Note: The Circle of Confusion is diminished with a wider perspective of the subject.
