Uranus & its Moons
Composite image made by combining two separate output from different exposure videos.
Taken on 29 November 2019, at 23.23 UTC (overexposed) & 23.17 UTC (normal exposure), with Celestron NexStar 6 SE SCT and ZWO asi224mc Camera. Video captured in SharpCap, stacked in AutoStakkert, then processed in PSP8, Registax 6 and LR. The moons were copied from the overexposed image & pasted onto the enlarged normal exposure image, & tidied.
Uranus has 27 known satellites, but only 5 are large enough to be relatively easily captured with a backyard amateur telescope. The names of these satellites are chosen from characters in the works of Shakespeare and Alexander Pope
The Uranian satellite system is the least massive among those of the giant planets & have relatively low albedos; ranging from 0.20 for Umbriel to 0.35 for Ariel (in green light). The moons are ice–rock conglomerates composed of roughly 50% ice and 50% rock. The ice may include ammonia and carbon dioxide.
