Jupiter + Moons 09-04-2017 at 0106 BST RS stack size best 600 of 1000 frames avi ISO 800 BYEOS capture pscrop

I made this image by using Registax6 to stack 600 frames from a video that I captured yesterday. The Great Red Spot is just visible and the 4 moons are (from bottom left to top right): Europa, Io, Ganymede; Callisto. A Canon EOS 60D was used mounted onto a Skywatcher 200 reflector.

Done
