“GRB 080319B was a
gamma-ray burst (GRB) detected by the
Swift satellite at 06:12
UTC on March 19, 2008. The burst set a new record for the farthest object that
was observable with the
naked eye:
[2] it had a peak visual
apparent magnitude of 5.8 and remained visible to human eyes for approximately 30 seconds.

As
Angelo said, and
toobfreak nicely corrected, the “farthest object visible with the human eye”
remains ... the Andromeda and M33 Galaxies ..
I used to have a 4-inch reflecting telescope as a kid (saved for partly out of my school lunch money) and I dreamed of becoming an astronomer. Unfortunately, living in a NYC suburb, I don’t think I ever saw these galaxies — at least not outside of the Hayden Planetarium.
One of the nice things about those days was going out to a quiet school yard or public park, setting up, and sometimes showing off before the older girls and even local punks who sometimes came around to watch. One night I discovered what looked like a huge crack on the mirror surface at the bottom of my open-ended Bakelite telescope. Checking more carefully, I discovered it was a flat ice cream popsicle stick one of the local wise guys threw down the open end of my beloved treasure.
I think is was done by some killjoy like
esalla.
