Uranus and its Satellites Retrogradation Curve

Image Description and Details :

I present to you a study on the retrogradation curve of the planet Uranus and its satellites made from December 2020 to February 2021.
Retrogradation, or retrograde movement, is the recoil that a celestial body seems to describe when observing it from distant stars.
It took 8 nights to image the planet with 50 luminance images of 10 seconds each in bin1 + 20 RGB images of 2 seconds each in bin2 and after assembly, process and annotations of the positions of the planet by date I looked for the position of the satellites visible on these images.
So on these images we can distinguish Oberon and Titania, and from time to time we see Umbriel.
