Whatever it is, it's a jiggled-up, overexposed version of this. Not quite as weird, but the instrument pointing logs would be of great utility here.

There's lots of them, and some have different speckles with different filters
Is it an internal calibration? Or Calibration using the Sun or something like that? Doug |

If I'm not mistaken, that may be an image of the calibration lamp. WAC has a calibration lamp (IIRC, WAC design was inherited from the Voyagers) while NAC has no such thing.
That bright middle band does somewhat resemble a tungsten wire in a lamp, defocussed of course. -------------------- |

Here's an exploded view of the wide angle camera, taken from 2004_PorcoWest.pdf:
Note the calibration lamp on the left, in the front of the optics. -------------------- |

Excellent explaination, ugordan... but I prefere Cugel version!
   (remember that in the original 2001 book, monolith was near Saturn!). -------------------- - Marco -

The Monolith in the novel wasn't just near Saturn, it was on Iapetus in a large white "crater" and the Monolith ETI had something to do with making the moon so bright on one side and so dark on the other - a kind of semaphore signal to humanity. See here: http://en.wikipedia.org/wiki/Iapetus_(moon...etus_in_fiction In fact none other than Donald Goldsmith and Tobias Owen speculated in 1980 that Iapetus' condition might be artificial: http://en.wikipedia.org/wiki/Iapetus_(moon...s_is_artificial Even Iapetus' discoverer, the real Cassini, noted its dark and light halves in 1671: http://en.wikipedia.org/wiki/Iapetus_(moon...tone_coloration -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
