The farthest thing you can see with naked eye is Andromeda Galaxy at 2.5 million light years. With binoculars you can spot the Virgo galaxies at about 50 million light years. With an 8 to 10 inch telescope this object 3C 273 is probably the most distant object you can observe visually at 1.9 billion light years !!! This quasar is about 12 to 13th magnitude and its light has been travelling across space to go down my telescope for about half the age of the Earth itself.
