March 2003 - Jupiter's Moons - Mutual events
Roughly every 6 years the orbits of the four bright moons are nearly edge on to our view and the satellites can be seen going behind or in front of each other. These animations and light curves show some of those events.
2nd March 2003 
ToUCam. LX-200 + Televue x2 Barlow. Approx 150 frames.

Freshly collimated telescope!
5th Feb 2003 20:39 UTC
ToUCam + IR filter. LX-200 + Meade Barlow f20. 1/25 Gain 30% Sat 75%
Approx 200 frames processed in Registax. 50% resize of final image

Still significant aberration problems I think due to poor telescope collimation and use of a cheap Barlow.
