There is no good time left tonight, so the next chance — tomorrow night (Oct 11 evening – Oct 12 dawn) — is shown.
Moon tonight: New moon (age 29.2 days, 0% illuminated) — Little moonlight — a good time for faint objects
Hours of full darkness (end of astronomical dusk to start of dawn) when it is above 15° — the darkest sky, mostly clear of buildings and trees.
