has anyone here worked on something that would render astral bodies, like
stars, constellations, galaxies, planets, taking into account the latitude and
longitude of the user?
I'm tasked with doing something like this, in a browser. If there was some REST API
I could consume and then render the horizon and the astral bodies, that would be
awesome, apart from that I would require the actual equations for calculating
their position above or bellow the horizon...
Thanks for any tips on this,
