Why Astrogram?

The longer story

Every astrophotography image has a story behind it. The target you captured, the equipment you used, the hours of integration, and the countless celestial objects hidden within the frame are often just as interesting as the final image itself. Yet sharing all of that information is usually a manual, repetitive process involving image editors, note-taking, and lengthy social media posts.

Astrogram was built to simplify that workflow.

Upload your image and session details once, and Astrogram automatically generates a beautifully designed infographic exposure card showcasing your image, equipment, filters, exposure settings, acquisition statistics, and capture information in a format designed for sharing. It can even generate social-ready captions to help you publish your work faster.

Want to explore what’s actually inside your image? Astrogram can plate-solve your frame and create an interactive Stellar Map, automatically identifying galaxies, nebulae, star clusters, stars, and other catalogued celestial objects within your field of view. Generate customizable annotations directly on your image, explore object information, and discover how far away these objects are with integrated light-year distance data.

Everything updates live in your browser, allowing you to preview your infographic card, annotations, and stellar map before exporting. No design software, no complicated workflows, and no subscriptions to manage.

“Just upload your image and transform a single astrophotography session into a complete visual story.”
