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.

Unprocessed view hot off the scope: 50 minutes into lunar eclipse, still in penumbral phase. Now is a good time to look outside :-) (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)
