At last a decent night which allowed me to test the new ZWO ASI120MM-S,USB3 version of the ASI120MM,faster and integrating hot pixels correction. With the overclocking possibility,integrated within Firecapture,allowing me to reach 73 frames/seconds at 1280x1024 resolution .... !
So full frame is now systematic,used at dusk with Saturn and at dawn with Uranus (of course I was only imaging at 12 frames per second for the latest).
That is also my first try at Uranus with the Dobson 320mm I'm using since two years - but of course in 2012 and 2013 I could image Uranus at Pic du Midi with the one meter telescope.
Anyhow here it is,this small blue dot which moves me every time when I see it,so small,almost fragile for a giant planet four times bigger than our Earth ... Uranus with no clear details except for the bright North pole in my opinion,along with Ariel,Umbriel,Titania and Oberon (brightness enhanced) which appeared clearly despite Oberon being mag 15,and a 12.7 mag star wandering in the field:
