Great Conjunction +3

Today was the first clear evening when Jupiter and Saturn were visible so I had to record the event. It was numbingly cold so I tried to be quick.

I am not sure what the light to the bottom right of the left hand planet might be. It appeared on most images and was independent of the lens used. Any explanation from astronomers please?

The extra is Arran from Ayr beach with Goat Fell, the highest point on Arran at the centre of the picture.
