Introducing OneSky Forecast!

Yeah, we messed up. We had been using "Astronomy" for all our products for 20 years and never thought for a second that calling something "Astronomy Weather" would be more overloaded than terms like "3D" and "AI" (okay, maybe not that last one).

So, starting today, Astronomy Weather will now be known as OneSky Forecast! That's right, same product, new shiny, potentially more SEO-friendly name.
