In spite of the moon last night, I went out to dedicate some time to observing Jupiter. I was treated, not that I planned on it, to an Io transit of the planet.
The skies were nice and clear and the air was pleasantly cool. At first glance I could see one of Jupiter moons very close to the planet's limb and I watched as it started to pass in front of the planet. I quickly connected a camera to my telescope and started taking image about every 30 seconds. The air was very unstable at around 9 o'clock but it would pop into focus for a few seconds. This improved through out the night. All together I got about 201 images of varying quality. I can make a movie, but it's going to take some processing.
It was one of those nights when everything seemed to work properly and the skies did too for the most part. As Io was approaching Jupiter's exiting limb with it's shadow following, the clouds moved in from the south to interfere with my pictures. I still managed several nice images through the thin clouds, but it fouled up the exiting of Io from Jupiter .
The process took about two and a half hours or so. Io entered Jupiter around 8:45 to 9pm and exited close to midnight. I used my DSI Pro with a red filter and my mount was tracked with "Carte du Ciel" and ASCOM drivers for the Orion Atlas EQG mount.
I'll try to post some images in a day or so.
