Here attached you can find an image of Uranus taken this morning under a
lot of fog and seeing fair/good.
Because it was just an experiment, no orientation reported.
A lot of troubles to find it and focus the image.
I'm not sure about features revealed; if I'm not mistaken, Uranus should
be regular and omogeneus.
So, I think it's better to wait for other images. Welcome any
future observation from any of us.

Hi all, here are some first results on Uranus. Images are not really
"self-speaking" ! I see a brightening on all images of the south pole, which
you may also see depending on which screen you're looking at (more visible
on a LCD laptop screen), but I have no proof that this just not any kind of
The C14 is used with a 2x barlow (F/22 theorically). The ATK is in normal
mode for the RG610 image (1/5th second with 80 % gain) and in long-exposure
in near IR (400 to 500 raws at 0,5 sec.).
Some reference professionnal images that show the brighter south pole can be
Pic du midi in 2002 (this one is a good reference of a ground-base I band image) :
(some Neptune and Pluto images as well !)
HST last year :
It would be worth rotating the camera in a next observation, to see if the
zone also rotates, for example, but this is clearly a very hard observation
(more easy to image Venus's surface ;-)) )
