2004/3/28 03:10 EST. Three shadows and a moon on Jupiter. The two images were take several minutes apart. Seeing was bad and humidity high. The shadow at the lower left rim of Jupiter was invisible in the eyepiece -- it only showed up after image processing. Sony camcorder (hand held to the eyepiece), 8"/f6 Dob, 9mm eyepiece. North at bottom, west to the left. From Green Tree, Pittsburgh. 400 frames stacked with Registax.

Europa Transit. 1999/10/26 1-2am UT. Europa's shadow is the small dark dot in the first few images (above the upper band, to the left). When Europa moved closer to the edge of Jupiter, it showed up (the 4th image): an indication that Jupiter's limb is darker than the center. Images taken with a 8" Dob and a camcorder. (In case you can't see Europa in the last few images, brightening the display may help)
