From Ashburn , Perseus Double Cluster is difficult to observe as it will appear no higher than 19° above the horizon. It will become visible at around 21:05 (EDT) as the dusk sky fades, 19° above your north-western horizon. It will then sink towards the horizon, becoming tricky to observe after 21:14 when it dips 18° above your north-western horizon.
