View Selection
Direct view is presenting the image as it would be seen through a binocular or any other erect-image system.
Inverted view is typically provided by a Newtonian reflector telescope.
Mirrored view is presenting the image as it would be seen through a Schmidt–Cassegrain/Maksutov/Refractor telescope with a diagonal adapter.
Credits
The algorithms to compute the positions of the Galilean Moons used in this application are based on the jsaa project (Javascript Implementation of Astronomical Algorithms) which, in turn, is based on algorithms published by Jean Meeus on his Astronomical Algorithms book.
