I think we're seeing issues of refraction from shooting through the windows of the capsule. That's causing the glowing or blooming effect from the point light sources. What I thought were possible galaxies look more like distorted stars from the refraction. I finally found a higher resolution image. All of the brighter point sources have that diffraction. It looks like some trailing of the stars as well.

That link is a nice visualizer. On the day of, the live cast announcer stated we were seeing Venus in the feed from the GoPro. But that seems incorrect, and it looks more likely to be Mercury.
