The open star cluster IC 4756 (mag 5.0) in Serpens will be well placed, high in the sky. It will reach its highest point in the sky at around midnight local time.
At a declination of +05°27', it is visible across much of the world; it can be seen at latitudes between 75°N and 64°S.
From Fairfield, it will be visible all night. It will become visible around 21:55 (EDT) as the dusk sky fades, 37° above your south-eastern horizon. It will then reach its highest point in the sky at 00:55, 54° above your southern horizon. It will be lost to dawn twilight around 03:59, 35° above your south-western horizon.
At magnitude 4.6, IC4756 is too faint to be seen with the naked eye from any but the very darkest sites, but is visible through a pair of binoculars or small telescope.
The position of IC4756 is as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| IC4756 | 18h38m50s | +05°27' | Serpens Cauda | 4.6 | 51'59" |
