Most seeing forecasts are designed for professionals and can be overwhelming for amateur astronomers. We built Astro Seeing to make this data accessible to everyone — whether you're planning your first telescope session or your hundredth.
Instead of checking multiple weather sites and trying to interpret atmospheric data yourself, we aggregate forecasts from multiple sources and present a clear consensus on whether tonight is good for observing.

Partly cloudy nights no longer read Excellent: above 20% cloud a night is Good at best, above 40% Fair at best, and more cloud always scores lower. Best Window is graded on the same scale as the night, counts the moon only while it is up, and humid nights are marked down less. Tonight's cards use tonight's dark hours, not the current hour. If the server can't be reached, the app shows your last forecast instead of an error.
