While camping, I noticed that if you look long enough at almost any star, you start seeing some tiny, subtle colors in that star. Even crazier, they sometimes flicker between more colors. In my case orange, blue and something like cyan.
Besides constellations, what else could you observe regarding starts, with the naked eye?
I don't think redshift applies to stars, as all the stars we can see are in the milky way and not moving away from us, not sure of there's any galaxies you can see with the naked eye
It does apply, technically, but yeah the effect is too small to see with the naked eye
A few nearby galaxies are visible, most notably Andromeda, but still redshift isn't naked eye visible for these
