Planet very difficult to capture, made capture with the camera zwo asi 290mc + C11edge HD + powermate 2x + powermate 2,5x + powermate 4x. Registered with sharpcap + registax + photoshop. There was little change from the original photo, just a few touches to improve contrast and reduce noise

The first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star. Uranus is 4 times wider than Earth.

Uranus is one of two ice giants in the outer solar system (the other is Neptune). Most (80 percent or more) of the planet's mass is made up of a hot dense fluid of "icy" materials - water, methane and ammonia - above a small rocky core. Near the core, it heats up to 9,000 degrees Fahrenheit (4,982 degrees Celsius).

All of Uranus's inner moons (those observed by Voyager 2) appear to be roughly half water ice and half rock. The composition of the moons outside the orbit of Oberon remains unknown, but they are likely captured asteroids.
