Hi §AB, Rob K & All,
Wow that skymap.org is a fantastic resource -- I've never seen it before but I can tell it's gonna be a frequently visited site for me -- thanks for the link §AB.
In addition to the link Rob K provided, if you are into Quasar and BL Lacertae object hunting, this is a more complete list though most will require very large telescopes:

Next Autumn/Winter I'm hoping to have a go at a few of these:
J01.03 HYA 0937-183 09 39 51.2 -18 32 16 QSO
2.400 16.20
CSO 38 LMI 1009+299 10 11 55.7 +29 41 41 QSO
2.620 16.00
HE 1104-1805 CRT 1104-180 11 06 33.6 -18 21 25 QSO
2.319 16.20
HE 1122-1648 CRT 1122-168 11 24 42.8 -17 05 18 QSO
2.400 16.50
B2 1422+231 BOO 1422+231 14 24 38.1 +22 56 01 QSO
3.620 16.50
The figures in bold are the red-shift (z) and the final figure is magnitude. All of them have red-shifts over 2 and in "look-back" time are about the 10.5 to 11GYR mark.
The one at 3.6 is about 12 GYR
-- though it will be a very difficult target due to low elevation at culmination. The one in Leo Minor suffers the same problem -- though, you never know 'til you have a go. I'd be surprised if the Hydra/Crater ones
aren't visible in 18" as they culminate not far from zenith.
My present record holder out of the list at the link is:
Q 1224-1116 VIR 1224-112 12 27 24.9 -11 33 35 QSO
1.979 15.40
Which is 10.3 Gyr "look-back" time. With 18" in near pristine conditions, I can hold it with direct vision pretty easily most of the time -- A.V a doddle. It got a run in Mar/Apr Deep Sky Delights p 64. I'd reckon 12 -14" would pick it up in very good conditions.
Best,
Les D
