Today marks the 30th anniversary of Voyager 1's flyby of Jupiter. On March 5, 1979, Voyager 1 flew through the Jupiter system providing a wealth of information of Jupiter, its magnetic field, and moons. Thanks to Voyager 1, the Galilean satellites became worlds with real geology and amazing vistas. Voyager 1 also revealed Jupiter's ring system and Io's volcanism for the first time.
I've written up a longer post about the encounter with Io on my blog, which also has an animation of the flyby: http://gishbar.blogspot.com/2009/03/30th-a...1-flyby-of.html -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

High resolution mosaic from Voyager 1. Resolution is around 3.5 km/pix. Color is from CH4_JS, clear and orange filter.

Great work! If I might suggest something, flat fielding the images would get rid of the bright corners in the images.

QUOTE (tedstryk @ Nov 20 2009, 03:36 AM)  Great work! If I might suggest something, flat fielding the images would get rid of the bright corners in the images. Thanks! I used only the dark frame subtract from these images. Flat fields (which I have) cause partially destruction of the details. Normally I use the images from dark side of Neptune or Saturn. Yesterday I downloaded the plaque images, but I don't see any advances over the dark side images. Maybe the problem is in the setup, so I'm still trying new procedures. -------------------- |

QUOTE (machi @ Nov 20 2009, 11:32 AM) ThankFlat fields (which I have) cause partially destruction of the details. That doesn't sound right. They should only affect vignetting, dust rings, and other static noise (differences in sensitivity, etc.) in the instrument. Do you mean the introduce even more noise into the images? When you say you use images of Saturn/Neptune dark sides, how do you get a flatfield out of them? -------------------- |
