Why do my sprites/textures darken whenever I move my camera?

I have a tile map that is simply a grid of 290x290 sprites. Whenever I move my camera, it darkens ALL of my sprites. The GUI does not darken at all, and seems fine. It only seems to be the single pixels I have scattered about (blue 1x1 pixel stars in a black outer space background)

I imagine this has something to do with blurring of adjacent pixels (which are black, thus causing it to darken) because there also seems to be some kind of blur effect where the pixels appear as though they are turning from a single pixel dot to a blurred line (similar to going into warp speed and seeing a star blur into a thin line).

I cannot show any screenshots, as this doesn't actually occur. Any screenshot will produce a normal result- nor blur, no darkening of pixels, nothing abnormal. It all seems to be anytime the Camera moves, no matter the speed, no matter the angle, no matter if the sprites are Point, Trillinear, etc.

I have more detail on the problem here:
