Camera view
There are up to four different camera views available, depending on the current location.
Free
The free camera view holds the orbited body always at the bottom. This makes controlling planes easier.
Orbital
The orbital camera view has always North at the top and South at the bottom. When a craft is in an (near) equatorial orbit the orbited body is always viewed from the side.
Chase
The chase camera view is always relative to the craft. So if the craft is rotating, the camera does this too. For docking it is recommended to use this view, as the controls don't change.
Auto
The auto camera view switches automatically between the free and orbital view depending on the orbit. Usually at launch it is in the free view and as soon as the periapsis gets high enough it switches to the orbital view. It also switches back to the free view, when the periapsis gets to low. The minimum periapsis to switch to orbital view depends on the body:
