Re: Show a line indicating geographic position

Thanks for the advice Selden. I have created a long thin model and attached it to the Earth as suggested.

In order to achieve a 180 degree field of view I need to have four different views of each scene (front, up, left and right). It does not seem to be possible to achieve this using celest...
