I've written a few times about Astronomers Without Borders (like here) -- they're a non-profit group whose aim is to bring people together via astronomy. The more folks they get looking up, the better. Sounds like a good plan to me, which is why I support them. To raise money, they've partnered with Southern Stars, the company that created the wonderful planetarium app Sky Safari. Until the end of the month, the app is discounted, with 30% of the proceeds going to AWB. I use Sky Safari myself all the time, and I really like it. The basic version is $1.99 (normally it's $2.99), the Plus version is $11.99 (normally $14.99) and the pro version is $39.99 (normally $59.99). You can download it via the Apple Store, and there's an Android version as well.
Another item they're using to raise money is something I think is pretty cool: solar eclipse ...
