This topic will contain images & discussion of same as they arrive during the extended download period. Similar threads will be opened in coming months as required as acquired data & discussion proceeds.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Yes the approximate region on the Pluto maps would be between -90 and +90 longitude. On my map (centered on 180 longitude) this would be within 90 degrees of the left and right edges, or the left quarter and the right quarter. The latitude range as Phil pointed out would be not quite all the way to the poles, related to how many Pluto radii Charon lies at. It would be interesting to map this out in terms of the illumination, being proportional to the sine of Charon's angular altitude from each point on Pluto's surface. This altitude reaches a maximum at the zenith at latitude 0 longitude 0.
We could also import a Pluto map into Celestia, position the observer near Charon (on its Pluto facing side) and take a look at what portions of Pluto show up. This Charon illuminated portion will be fixed as a function of time, even though the sunlit phases of Pluto and Charon will vary. Meng-'Po Macula is at the best location. -------------------- Steve [ my home page and planetary maps page ]
