In previous videos Ursu's been seeing blue planets behind or next to the moon.
The image below, taken from a photography forum discussing problems with lens reflections, was taken by a guy (Ben_B) who also explains how he created it.

In many of his videos, especially the one where he uses a camera with lower resolution, you can clearly see the features of the-man-in-the-moon/the-rabbit-in-the-moon.
In one video (the one with the silent homeless guy) the blue thing can't even be seen until the angle between the camera and binoculars is adjusted.
