Sycorax was discovered with the 5m Hale telescope at Palomar in September 1997 just 23 years before this image was taken on 2020-09-14. The satellite is only 150 km in diameter and was 2978 million km distant at that time, when it then had a V magnitude of 20.7. Sycorax is marked with the cross-lines; the star indicated with an asterisk is Gaia EDR3 75009958852730496, catalogued at magnitude g=19.03. A good number of background galaxies are also visible in this image, ranging in magnitude from 18.5 or so down to perhaps 21.5 though I have not yet identified and found good data for any of them.
The background glow at the top-right of the image comes from Uranus itself which is well outside the frame.
