Here is a GIF of two images (each a stack of 300+ frames) taken with my iPhone attached to a Celestron NexStar8SE telescope on the night of April 29, 2016.
These images were taken about 20 minutes apart and show the movement of Europa (left), Io’s shadow, and Io (right) along with the Great Red Spot.
For information on how I take these images with my iPhone, please see my post on Smartphone Astrophotography.

Well done. 👍
Saw this same view that weekend in Ottawa through my new Orion 90 mm. Thanks for sharing.
