Io transit of Jupiter

[yeti monster]

Webcam capture, 2x 2x Barlow stack, TAL-1, manually tracked.

I could only see 3 moons beside Jupiter, through the wee skymax, so I was hoping to catch a transit, rather than an occultation:

From 30th Novemeber, this single 2x Barlow capture has Io & Europa. I had to ramp the gain to catch the moons, then layered the Lo gain image of Jupiter onto the image:

Good catch
