Saturn and its moons

moons-plus-saturn-annotated.jpg

As seeing was not so good, I used the opportunity to image the moons of Saturn using the webcam at maximum sensitivity, while later adding Saturn itself, acquired at lower sensitivity. The moons and their respective magnitude are shown. Mimas (mag 12.8) was overshadowed by the blowout of Saturn and Hyperion was simply invisible (mag 14.1!). The sizes of the moons in the image nicely match their increasing magnitude. The Celestron C8 was used without Barlow in combination with the Philips Toucam.

The same view in HNSky:

As saturn was close to the moon, my telescope fogging up and seeing was poor, this is the best I could do.
