This is my best ever image of Jupiter, taken in February 2014 in Fayetteville, Arkansas on a night of incredible seeing. If you look closely, you can see Jupiter's volcanic moon Io to the right of the planet.
Taken with a Celestron C6 SCT, Celestron AVX mount, a 2x Barlow, and a ASI120MC planetary/lunar imaging camera. I recorded several minutes of video using the ASI120MC and then stacked the sharpest of the resulting still frames to produce this composite image.
