Star Chart.

24 x 14".

Made using ArcMap and ArcGIS Pro, 2017.

Tutorial guide for how to make this star chart using ArcGIS Pro.

Star charts assume all celestial features exist on an imaginary sphere surrounding the earth, complete with poles and an equator. This means that they can be plotted and projected in the same manner as terrestrial maps. I found most of this data already compiled and converted from Declination and Right Ascension into Latitude and Longitude. I extracted the polygons for the milky way from an SVG image file.
