I might be wrong but I have read that the great galaxy in Andromeda can be visible to the naked eye under ideal conditions. Ditto for another in Triangulum although it is much fainter.
Do you know of a simple web site that shows us the different galaxies in their relationship to ours?
Indeed. But the question was for stars. Any individual star is ver close on a cosmic scale. Heck, the Andromeda galaxy is close by cosmic standards.
A few people have claimed to observe galaxy M33 (Triangulum) unaided. It's close enough to us that its angle of size in the sky is greater than that of the moon, but it's surface brightness is very low. I have never been able to find M33 with binoculars.
About 4 people say they have observed galaxy M81 unaided, which is 12 million light years distant. If this is true, the conditions would have to be extraordinary, and there are probably only a handful of people on Earth who's vision is that sharp.
I first saw M31 when I was a teen. I have been watching it ever since, mostly in amazement that it is still visible even when stars dimmer than mag 4 are lost in the light pollution.
