Windy is a wonderful app and I am enjoying it very much.
However I can not find light pollution map or bortle scale map on it.
So I can only switch to another site(like this) to ensure where I can take photos of milky way and stars and go back to Windy to check when the cloud conditions can meet shoot requirement.
If Windy develop above functions or someone can develop that plugin, which could be layers of VIIRS or World Atlas 2015, it will be very nice and convenient.
Hope that day come true, lol.
