Uranus with 4 moons

At the moment Mars is in high demand, so I thought to try Uranus for a change and for the first time. It was getting light already, so just a few captures. It was very cool to see that blue/green disk but with processing I noticed the moons to my surprise :D
They are Ariel, Titania, Oberon and Umbriel (mag 14 - 15). Miranda is not showing, it's in the planet glow. A job for a next time.

But I am so stoked that I have captured those 4 moons.

And although I used the TeleVue Powermate 2.5x barlow, which makes my system focal length around 5000mm, it all is still without guiding. When I bought my mount, I doubted it cause it is expensive ... and I have zero regrets now :)
