Jupiter


A composite of two sets of video exposures, captured on February 21, 2004. Each set consisted of 100 individual frames assembled with Registax software. Because of the difference in brightness between Jupiter and its moons, one set was used to create the image of Jupiter and the other was used for the moons. The images were captured with a 10-inch Newtonian, 2x Barlow and monochrome CCD video module.
An annotated version of the above image. Some additional detail of Jupiter's equatorial bands was extracted from the video as shown in the inset. Although difficult to distinguish from noise in the image, there appears to be an atmospheric disturbance visible in the enhanced image.
   
An image of Jupiter captured on March 14, 2004 as its moon Io casts a shadow across the cloud tops of the planet.

The image was constructed from approximately 100 video frames and composited with Registax software. The processing appeared to introduce some "ringing" around the image of Io's shadow which manifested as the lighter areas around the shadow.

   
An annotated version of the above image. Note that Io appears as a faint white dot just to the right of Jupiter's limb in this image. The object to the left of Jupiter appears to be Ganymede, but does not exactly match the position calculated by my planetarium software.
