Description

You can see the bright/white massive polar storm. Unlike the other planets in our solar system, Uranus is tipped on its side. This leaves the sun shining non-stop onto its north pole during its long summer, likely resulting in widespread atmospheric change.
Uranus is an unusual & difficult target in lucky imaging, I had to use an obturation value of 150ms (6fps only) and gain 400 with the IR642nm filter & ASI178MM for the luminance and 77ms + gain 333 with the ASI462mc for color... despite having a 15" telescope!
