Pulsating UFO snapped over Exton on January 2018

On January 2, 2018, a witness was outside to take some photos of the Moon in Exton, eastern Pennsylvania. In the night sky, he saw an unusual pulsating light. What is it?

Witness report:

I went out to view and photograph the super moon visible on the night of January 2, 2018 in Eastern Pennsylvania. I noticed an unusual, rapidly pulsating star to the lower right of the moon, in the south west portion of the sky. This was not a plane or a satellite. It remained very bright and maintained it’s position in the sky for hours. It was in the vicinity of the constellation Canis Minor. I used an amateur Meade telescope to get a better look at here. Through a strong lens, it appeared to be a disk of rapidly rotating lights that flashed as well. These lights constantly changed color. There was a dark void in the center, though at times I noticed some specks of light in the center. I recorded a video, using an iPhone against the eye piece in my telescope. I also took numerous stills from the video as the video shifts due to an unstable tripod. I will attach all of the content below. Hopefully you can offer an explanation? Thank you.
