I think a parameters submenu of the astronomic menu, with the setting being 
permanent until its changed, would be fine. That'd be no less clunky then it 
already is to set the latitude and longitude via goto in exploration mode.

That's essentially true for calculations which are based on the current time, 
but, for example, as already discussed, it's not very useful to know about past 
events like when sunrise was this morning. Perhaps functions which aren't based 
on the current time should be split and always refer to the next event, e.g. 
have separate functions for sunrise, sunset, moonrise, and moonset, and always 
calculate the next event rather than the potentially past event for the current
