Stanislas Maksymowicz,Luigi Morrone
Here is a report for uranus performed last 21st october with the 150mm refractor.
Images were good,transparency of sky too with a great amount of moisture.
The albedo variations noted were not coming from the misalignment of the scope as a neighbour star observed at the magnification exhibited a perfect diffraction pattern at the eyepiece (first ring was just ondulating with the seeing).
Therefore Something on the planet disk well present.
Still the p le darker than its neighbour zone also was there.
The period became worst after 21H30UT,images well agitated.

Under good seeing conditions. The North Polar cap results to be clear. No atmospheric activities visible.
