Default Oldest light seen by anyone here

As I newbie, I spotted the Beehive cluster the other day, and that has
stars in it over 700 light years old.

Quite impressive thinking the light emanated from the source during the
middle ages.

What's the oldest light anyone's seen here ?

3C273 : 2 billions year old
That's the brightest quasar of the skies, and I saw it with an 8" telescope.

I've seen M31 naked eye and 3C273 (1500 million light years) with a 10
inch telescope.

The Double Quasar in Ursa Major through an 18" dobsonian. Not sure of the
age, 7+billion light years. Unthinkable?

To think I was impressed with 700 years old. Still I can conceptualize
that a lot more than 7 billion light years !

Have you tried APM08279+5255? Its receding at 92% velocity of light
and some 12 billion light-years away !

I've looked via my CCD

at http://www.astroman.fsnet.co.uk/qimages.htm !!!

That's cheating! Very impressive achievement, though. I thought we were
talking about eyes at telescopes. Has anyone seen a gamma ray burst yet,
rather than just catching the image on CCD?
