About Astrographer

Astrographer is an app to help astrophotographers find the right gear and keep a record of their astrophotography journey!

About me

I'm a software developer and beginner Astrographer based in the UK. I built the core features of Astrographer for myself as I was learning the hobby and thought they might be useful to others!

You can find me on Twitter or email!
