Thanks for looking and for your comment! Much appreciated. I also noticed the blue fringe. That seems to happen with either a longer exposure or higher ISO. I'm not sure why.
Chromatic aberration, also known as color fringing, is a color distortion that creates an outline of unwanted color along the edges of objects in a photograph. Often, it appears along metallic surfaces or where there's a high contrast between light and dark objects, such as a black wall in front of a bright blue sky.
