The open star cluster IC 4756 (mag 4.6) in Serpens will be well placed in the evening sky in coming weeks. On 2 July it will reach its highest point in the sky at around midnight local time, and on subsequent evenings it will culminate four minutes earlier each day.
From Columbus , it is visible all night. It will become visible at around 22:25 (EST), 37° above your south-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 01:26, 55° above your southern horizon. It will be lost to dawn twilight at around 04:43, 33° above your south-western horizon.
At a declination of 5°27'N, it is visible across much of the world; it can be seen at latitudes between 75°N and 64°S.
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 | 5°27'N | Serpens Cauda | 4.6 | 0'00" |
The coordinates above are given in J2000.0.
