Uranus takes so long to orbit the Sun (84 years) that is moves very slowly against the background constellations. It will therefore continue to be visible in the autumn evening sky for years to come.
On this November night, the seeing conditions were good enough for me to capture an image of Miranda for the first time. This moon is dimmer than the other four seen here, and at magnitude 16 it hard to detect.
4-second exposures were used to capture the moons, and 1/15-second exposures were used for Uranus so it would not be overexposed.
