Uranus Image 2018/12/10(UT)
Here is the uranus report performed last 10th
with the 235 cassegrain under good to average images.
Banding pattern there, but with a discontinuity near the limb as shown,
dark pole also seemed to be circled by a darker ring.
Brightenings at limbs each on the bright band circling the pole.
Albedo variation on the tropical bands as shown.
A good observation for not saying excellent,
better results with the 412x magnification (0.57mm exit eye pupill diameter,
which is the optimum for the present conditions).
The albedo scaling of features at the sketch was as possible respected.
