The Astrosky Ecosystem - Open Collective We're building an open-source ecosystem of social media tools for the space science & astronomy communities.

For the last two years, I've been paying for the Astronomy feeds hosting myself.

It has been a privilege to grow our community here, but I also shouldn't keep doing it for free 😅

That's why I'm delighted to announce that we now have a donations page on Open Collective! 🔭☄️ #astrophotography

Congratulations on the new Astro Plot of the Week!
