Star data from : [YaleBrightStarCatalog (Bretton Wade)](https://github.com/brettonw/YaleBrightStarCatalog/blob/master/bsc5-short.json) (MIT License, Copyright (c) 2016 Bretton Wade)
Constellation data from :[Lizard Tail (Isana Kashiwai)](https://www.lizard-tail.com/isana/lab/starlitnight/)
## Tips
There is one information that is not yet explained in the game : you can left click and drag to move around.
## Demo
You can check it out [on my website](https://www.penwing.org/assets/games/Astraea/web/index.html)
but here is a sneak peek :
