Thanks for that. I was just wondering if I'd be able to see Neptune or Uranus...I know it won't be a great image, but just wondering if I'd be able to make it out. Finding it will be fun!

Uranus @ mag 5.73 is a naked eye object from a dark site, however (besides
the current moon phase) it is located just NW of Phi Aquarii @ mag 4.21
which will probably wash it out for naked eye. but should be in the same FOV
med/high power ep. Neptune is a lil harder to locate so try a high power on
it to bring out the lil more of it's disc appearance. When I first tried to find
Neptune years ago, I searched for months before some one suggested a
higher power and bingo there it was... and there was me jumping around the
yard with glee!!! Both take on a pale blue kind of appearance and as above
are non stella compared to surounding stars, higher magnification here sorts
the gas gaint from it's stella suroundings.
Oh yeah I believe the most distant odject man can see with the naked eye
is M31 @ 2.9 million lightyears. The most distant object I can see in my
8" is quasar 3C 273 @ 2+ billion light years
