What Is That?

OK tonight I was very busy with the water heater that needed the thermocouple replaced. Bummer, but needed to be done. So I get out tonight about 11PM and start taking pics of the stars. Its late and I'm rushing the shots. Bad formula but here is the interesting thing. The blue dot you see in the blip is moving the opposite direction of the stars and that haze around it is in all the shots I took. I cannot locate it on Stellarium so it is not celestial. It is not a satelite because it moves too slow. Its not noise because it moves in the frame. I don't know where else to look and I didnt get that many shots of it anyway. I am stumped.
