Here are my first Uranus images of the new season,all taken under excellent seeing.
These are R+IR images and true color RGB's,wether taken with ASI224MC or ASI290MM.
All results show the bright north polar region,including the color images.

Here is the report of Uranus on the 14th october last performed with the 203mm cassegrain
under average to good images.
Arrows shown on the picture exhibit main topics:
- a brightening seemsly on the eq clear notch spreading from the limb.
- the relative dark p〓le. I am suspecting a hole into very brigth located at the p〓le
but the aperture in use didn't show sufficiently this feature.
Nextly I will try the 305mm hoping good images with more 400x magnification.
A thin dark fillet on the southern lattitude of the north temperate belt was conspiscious,curved indeed.
The south temperate belt was as dark as the north p〓le.
Difficult to say more,however the p〓le area will need〓 a special survey.

Under sufficient seeing condition. Quite good transparency. North polar cap clearly seen.
Umbriel ,Oberon, Titania and Ariel are visibile too.
