The open star cluster NGC 869 (mag 4.0) in Perseus, also known as the western half of the double cluster 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 57°07'N, it is easiest to see from the northern hemisphere but cannot be seen from latitudes much south of 12°S.
From Ashburn, it will be visible all night. It will become visible around 19:18 (EST), 33° above your north-eastern horizon, as dusk fades to darkness. It will be lost to dawn twilight around 06:25, 36° above your north-western horizon.
At magnitude 5.3, NGC869 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 NGC869 is as follows:
