I found this repo - https://github.com/DJBen/SpaceTime

It does azimuth and altitude / right ascension and declination - can swiftAA do this out of the box?

if so - do you have a snippet of code to share?

Hi John. Sorry for not following all the details, I am pretty busy these days. But to answer your question, yes, SwiftAA do this out of the box. These are the transformation of EquatorialCoordinates into Horizontal ones. Check the makeHorizontalCoordinates method of the EquatorialCoordinates class.

thanks Cedric, I'll share a gist when I get to it.
