[AstroPy] Setting and rising of a fixed object in the sky

[Thomas Robitaille]

Hi Javed,

Could you show the code you have written to use Astroplan? There are
ways to set up Astropy coordinates that are more efficient than
others, so maybe we can make suggestions to make it run faster.

Cheers,
Tom
