Ordered alignment
This mode is used to find pretty scenes in the skies of some planet or moon, such as when several moons are visible in front of a gas giant:



Alignment
This mode is very similar to ordered alignment, but it ignores the order of objects in space. In the case of a planet and its moons, it will find all alignments of those objects, even if some moons are hiding behind the planet. It is more suitable for finding alignments of planets in the sky, when you don’t know or care about their real arrangement in space. Such alignments are sometimes called “conjunctions”, though this is not exactly what the tool finds. The exact conjunction of 3 or more planets is impossible, but the tool looks for “approximate conjunctions.” In the following example I found all the upcoming conjunctions of Venus and Mercury, ignoring distance to each (in this screenshot Venus is farther than Mercury):


Transit
The next type of event is transit. Probably the most famous transit events are of Venus transiting over the Sun. In this mode, the first object in the list must be the observation point (Earth in this example), the next one is the object which serves as a background for the transit (the Sun), and the next is the object which is doing the transiting (Venus). Note that the angular precision is automatically set to the angular radius of the Sun (more exactly, to the sum of the angular radii of the Sun and Venus at the current date), and the time step is also calculated automatically. I manually set the start date to the year 1800.


Occultation
An occultation is technically the same as a transit, but where the transiting object is larger than the background object. For example, when Jupiter transits its moon Io (covers it from the observer’s perspective), this is called an occultation of Io by Jupiter. Like in other modes, the event finder allows you to find multiple occultations by the same occulting object. Shown below is an example of a simultaneous occultation of Titan and Rhea by Saturn (position of Rhea is highlighted by the selection pointer):

Eclipse
Eclipses are transits or occultations as observed from the sun. The first object in the list must be the sun (or another light source, as the tool allows one to find eclipses of one moon by another as viewed from the planet). In the case of a single-star system, the tool adds the sun automatically; but in multi-star systems you must add the star yourself. The next object is the one which is being eclipsed (ie. receiving the shadow), and the last one is the object creating the eclipse (that is, casting the shadow). The event finder calculates the angular precision and time step for this configuration, but again, this works well only for orbits which are not very elongated.





Other changes
Below is the full changelog for this version. Included in the updates is the option to reset all SE settings (except controls), which can be found in the F4 settings menu. After pressing the button, SE simply deletes the config/main-user.cfg file, replaces it with config/main-def.cfg and restarts. Of course, the default file main-def.cfg must be intact; you are not allowed to modify it. Upon restarting, SE also clears its cache and rebuilds shaders.
