Dear Friends,

The quasar 3C273 in Virgo is the brightest visible quasar from Earth and
with a magnitude of 12.8 is also visible with average amateur equipment.
Lying at a distance of two BILLION light-years away, it is the furthest
any amateur equipment can reach (and especially right from one's
backyard).

Further details including an image are available at

Hi

A lovely image...
..but for example http://www.guildfordas.org/observing/quasar_episode.html
~7 billion light years (I am not a member of the Guildford AS).

There are apparently quite a few others as well as AGNs that are observed,
imaged and monitored by amateurs.

Paul

to think these things are so far away and odd at the same time. Why
are there no closer quasars?

Here's another - Q1634+706 in Draco. Light travel distance: 9 billion light
years. Distance now: 13 billion light years. Observed in a 10" and should
be visible in an 8".

I believe the current theory is that they are the nucleus of very young
galaxies. Why there are no young galaxies in our direct neighbourhood is
left as an exercise for the reader

Hi:

Not much of an exercise. It's probable that these objects and their
galaxies are the product of the early universe. In our "modern times"
locale, you ain't gonna see QUASARs--the period of galaxy formation is
long over.

It is a great shot. Unfortunately your diffraction spikes line up with
where the jet might hope to be seen (roughly diametrically oppposite
the fainter of the two close in stars. I suspect it may be beyond
impossible for amateur kit to capture by it might be interesting to
try for...

Dear Friends,

A huge thanks for the various recommendations surrounding other
interesting quasars and which I will mark down for immediate imaging.

Nevertheless, I am delighted to see the thread that has been generated and
the really cool tips (targets) that have ensued. I am quite eager to
pursue PC 1247+3406 in Canes Venatici which I think (?) is the further
quasar found so far (over 12 billion light-yrs away and at magnitude
20.4).

Can someone enlighten me how to convert the redshift to percent of the
speed of light? Also, Ioanni, I do have the regular image (white on
black).

Anthony.
