Should we move away from PyEphem?

[kuntzer]

I ran into weird behaviours that won't be changed see here: https://github.com/brandon-rhodes/pyephem/issues/102 this affects twilight times.

This package, by the same author seems to be bit more flexible: https://github.com/skyfielders/python-skyfield

To be reflected upon...

After thinking about it for some time, I think it's fine for now. There will be a ~2 min discrepancy between predictions of twilight times, so we should be fine.

Yep, we don't rely too heavily on this tbh, so let's keep PyEphem running.

Okay, agreed. Close for now.
