[AstroPy] mollweide projection plotting (celestial sphere in Galactic coord) ?

[Guillaume Blanc]

Hi,

I'm looking in a python library to plot a mollweide projection of the celestial sphere with some points and lines between two points... I tried using healpy, but the projplot function doesn't work well, and the plotting options look limited (well, it's not the main goal of that library, actually). 

To try to be clearer, I'd like to plot some objects in a projection of the celestial sphere in galactic coordinates with the standard mollweide projection, and plot as well some "lines" such as the celestial equator and so on... 

I'm sure something exist somewhere to do that!

Many thanks in advance,
Guillaume Blanc
