The seeing was very poor this morning,so no rgb image was possible. Instead,here's an image taken with an 807nm ir-pass filter (passes 807nm and longer) showing Io and it's shadow. Io is very bright with this filter compared to Jupiter.
This image is the best 1000 frames out of 1200,taken with an IR807nm filter,20fps for 60 seconds and max gain through a PGR Flea3 camera,14.5" newtonian + 5x powermate.
