A script that finds the darkest position near zenith for a given time and date. And for fun a Script that plots the whole sky.

The cartopy builds inside anaconda are currently outdated I created an issue for updating it.

In the mean time, install the dependencies like this:

conda install geos
conda install -c https://conda.binstar.org/osgeo proj4

And then install cartopy with pip:

pip install cartopy
