I've been playing with the released raw ISS images (thanks to Bjorn for the img2png program!) trying to produce a better image near Huygen's descent location.

Here's what I've come up with. I started with images from two different imaging sequences, applied a Fourier bandpass filter, and stacked the images from the same pass. Because of different lighting conditions, or atmospheric conditions, or something, the images are significantly different, so I combined them as red and blue layers instead of just stacking further. Green is produced by the product of red and blue chanels, and a further contrast adjustment is also made.


I believe Huygens descent location is in the upper left corner. The correspondence with one of Rene's beautiful mosiacs is given here:


Unfortunately the geometry is different enough I can't really overlay the mosaic with the ISS image...

That's okay. I just noticed that tfisher didn't mention which flyby he got that data from, Ta or Tb. Either way it was before the landing. Tfisher, what is the image numbers on the images you used.

The images for one sequence are n1477488603_2, n1477488635_2, and n1477488667_2 (from the Ta pass); for the other are n148162483_4 and n1481624423_4 (from the Tb pass).
