Saturn and Neptune will share the same right ascension, with Saturn passing 1°08' to the south of Neptune.

From Cambridge , the pair will be visible in the morning sky, becoming accessible around 23:56, when they reach an altitude of 21° above your eastern horizon. They will then reach their highest point in the sky at 03:51, 46° above your southern horizon. They will be lost to dawn twilight around 04:22, 46° above your southern horizon.

Saturn will be at mag 0.6, and Neptune at mag 7.8, both in the constellation Pisces.

The pair will be too widely separated to fit within the field of view of a telescope, but will be visible through a pair of binoculars.

A graph of the angular separation between Saturn and Neptune around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

The coordinates above are given in J2000.0. The pair will be at an angular separation of 132° from the Sun, which is in Cancer at this time of year.
