Might be interesting to redo the Cassini global cylindrical movie of Jupiter in color. The released version from the CICLOPS website was relatively low in resolution, yet the original was at higher resolution judging from one of the still images released. This is the 2-D interpolated movie I'm referring to. This has in fact been done as a part of a new Science On A Sphere presentation. The Jupiter animation looks great at higher resolution. The next thing I'm checking into is whether this movie from the Cassini Dec 2000 flyby is available in a stand alone version. The full 1.6 GB SOS presentation where the Cassini animation is embedded can be downloaded here. |

Now, I'm usually a RAW images man - I like putting together vistas that were captured in the very recent past, and 'hot off the press' if you like.
However, I've finally got around to playing with Bjorn's awesome IMG2PNG utility and have calibrated some early Cassini views of Jupiter (the difference between the calibrated and non-calibrated images is quite staggering). Due to the lack of any RED filters, the following view was constructed using a synthetic red (sort of GREEN minus BLUE, in effect). I'm really pleased with the result: Jupiter, as it appeared to Cassini on the 14th of October, 2000 Thanks Bjorn! -------------------- |

A comparison of an image from the PDS, before and after the IMG2PNG treatment. I've brightened both views quite considerably in order to make visible all of the crud that the calibration process removes:

Last of all, for the time being, a classic view of the Jovian giant, with the GRS emerging from the terminator:

Here's a 4-frame NAC mosaic from the 10th December 2000:

Thanks Ted! It took me a little while to figure out how to blend together the Io-centric and Jupiter-centric versions of this composite, but I got there in the end without having to resort to the Paint Shop Pro lasso tool!
Anyway, here's a two-frame mosaic from the 12 of December, with an additional enhancement to bring the limb out of the gloom slightly: -------------------- |

Very nice images!
Jupiter is one of the most photogenic objects in solar system. Image with Io is magnified or is it mosaic (is bigger than Cassini CCD)? -------------------- |

Jupiter is one of the most photogenic objects in solar system. It sure is! It's also tough to work with unless you have a rapid-fire camera, and Cassini's sure don't fit that bill. Great work on the images, Ian, they look very close in color to official images. Here are a couple of my recent processings: And an animated gif: -------------------- |

Knockout work again, Ian & Gordan! What amazing vistas.
