alien sky astrolabe

created this rough sketch of how the constellations are seen from alpha centauri years ago note emphasis on large lines making up long constellation and combinations of what we see as separate star patterns into one the aliens sky shows the sun as large star in cassipeia the harper on the map
so as the rhymme goes ,"harper, archer, water slayer,fear the slayer, death the bride, third sister, bright dancer to blind watcher"

proxima centauri i believe is somewhere at the bottom the map near the storm sister constellation between harper and archer
the orbit of alphacenturi B crosses the central halfas visible to a planet at 27 degrees axil tilt
supernovas the most important are marked on the sketch and bright stars would be important to a culture basing its calendar on the night sky and the two suns AB 81 year orbit across his sky by day and night
building a astrolabe of the centauri constellation still at foundation stage but more of art work than science project
