QUESTION

How to plot an ortographic projection of the celestial sphere with equatorial coordinates in python, for a given latitude?

Asked 2021-Feb-24 at 07:43

I am trying to obtain an ortographic projection of the celestial sphere, with equatorial coordinates, as seen from a certain latitude, as in the following picture:

(Grid obtained from Skychart/Cartes du ciel)

This image is a print of Skychart/Cartes du ciel, showing the equatorial grid for an observer at 23°S latitude. I want to be able to reproduce the exact same image in Python (apart from the dark blue background). My first attempt was to use CartoPy, setting the central latitude as -23, as follows:

First of all, your first image is Azimuthal Equidistant Projection. So that, it is quite different from your second plot (Orthographic projection). To get the plot (first image) like that using Cartopy requires some steps that are interesting to follow. Here is the code with comments that produces the output plot that I consider a good result.

Good question! I should add a new section to https://rhodesmill.org/skyfield/searches.html explaining this common behavior seen when subtracting two longitudes or right ascensions. The key to unraveling the mystery is to watch what happens to the angle difference at one of the moments that is showing up in your output as a phantom conjunction. I’ve attached a script which prints this for the very first event you print, between Venus and Aldebaran:
