While I'm at it, here is how the image looks with both channels separated and without any processing. Again, what I am looking for is the digital data, not a better source to scan.
While I'm on the subject of Pioneer 10 and 11, here is the abstract I submitted for the Lunar and Planetary Science Conference (which I will be attending this week). http://www.lpi.usra.edu/meetings/lpsc2011/pdf/1267.pdf It was written before my visit to Ames Research Center in January. I did find some better material to scan and some fragments, but I did not find the digital data I had hoped to. The most useful projects will likely be a high resolution mosaic using the closeup data from Pioneer 11 as it passed over Jupiter's North Pole and a sequence (perhaps to be made into a movie) of Jupiter rotating from above the North Pole as Pioneer 11 receded. Here is the poster I am presenting, which is a combination of older work and very preliminary processing.
Each image is designated by a letter. Here is a guide to the images based on those letters:
A. Pioneer 11 image C5 (Jupiter) Scans
B. Pioneer 11 image C7 (Jupiter) Scans
C. Pioneer 11 images C1 and C2 (Jupiter) Scans
D. Pioneer 11 images D1 and C2 (Jupiter) Scans
E. Pioneer 11 image D16 (Jupiter) Scans
F. Pioneer 11 image D19 (Jupiter) Scans
G. Pioneer 11 image D7 (Io) Digital.
H. Pioneer 10 image A24 (Ganymede) Digital
I. Pioneer 11 image D3 (Jupiter) Scans
J. Pioneer 11 image F7 (Mimas transiting Saturn) Scans
K. Pioneer 11 image F12 (Saturnian Rings) Digital
L. Pioneer 10 image B38 (Jupiter with “Little Red Spot”) Scans
M. Pioneer 10 image B39 (Jupiter with “Little Red Spot”) Scans
N. Pioneer 11 mosaic using data from images F33, F19, and F12-F5 (Saturn) Mix of digital data and scans.
O. Pioneer 10 image A2 (Jupiter – Great Red Spot) Scan
This is only the tip of the iceberg...
