Hi all, I hope this isn't out of place, mods please move or delete this if it is. I've started doing an acrlyic landscape painting set on the 'coast' of Tombargh Regio, Pluto (below - very much a work in progress). I want to get the sky accurate if I can, but I'm having trouble working out where Charon would be in the sky from a give location. Can anyone help? I'm having trouble even figuring out where the sub-Charon point is on the most recent images, wich would at least give me a start point.....

Full Version: Help with the position of Charon in Pluto's sky
Unfortunately, Charon is tidally locked to the opposite side of Pluto so from that view of the region, you would never see Charon. However, its also a painting and sometimes factual accuracy can be ignored for artistic intention.

Right, way back in planning the flyby, the geometry for allowing both Pluto and Charon to eclipse earth as seen from NH was the paramount concern for radio science, so Charon ended up being on the opposite side and not particularly close.
Never mind, I do an awseome Milky Way! Thanks guys :

Maybe I'm a tad inexperienced with Celestia, but I haven't seen that side bar before John. Is that an addon and if so, where could I get that?
one of the advantages of being the person that checks NEW addons
