Movement of #Uranus system over three hours against backdrop of fixed stars (moving about 19 arcseconds). 40 x 50 x 4 sec unfiltered mono in Celestron 8" at f/10.
Time lapse of #Uranus system over three hours. This view is centered on the planet to more clearly show the intrinsic movement of its moons.
If you like moving planets here is one of Saturn
I neglected to mention that the apparent motion of #Uranus in above animation is retrograde so it is dominated at the moment by our own Earthling observer position as we "overtake" Uranus in its orbit.

(I'm in some kind of hell now where I have to adjust the telescope tracking once per minute for the next 5 hours since it is such a tight fit on the sensor)
Hot off the scope: Ten minutes into partial phase. Brightness stretched to more clearly show the circular edge of Earth's core shadow #LunarEclipse
