Description
Picastro — Social media for astrophotography

Picastro is a purpose-built social platform for astrophotographers and astronomy enthusiasts.

No noise. No compression. No algorithms deciding what matters. Just real people, sharing real images of the night sky.

Whether you’re capturing your first star trails or processing a deep 20-hour narrowband image, Picastro gives you a place to share your work, learn from others, and actually enjoy the process.

Your images in full quality. Always!
Astrophotography takes time, patience, and precision. Your images shouldn’t be reduced to blurry, compressed versions of your work. Picastro preserves your images in high resolution — what you upload is what people see.

A real global community — not a content machine.
No bots. No fake accounts. No chasing likes. Picastro is built around a genuine community of astrophotographers who want to share, improve, and support each other. It’s not about attention. It’s about progress.

Learn naturally as you go. Every image on Picastro carries context. With StarCards©, you can see exactly how an image was captured — telescope, camera, filters, exposure time, and more. No gatekeeping. No guesswork. Just real insight from real people.

Built for beginners in astronomy and astrophotography and experts alike.

Starting out? You’ll find a welcoming space where you can share your first images without feeling out of place. More experienced? You’ll discover high-level work, detailed setups, and meaningful discussions. Everyone starts somewhere. Picastro meets you there.

Designed for mobile and tablet. Built for simplicity.
Picastro isn’t a complicated web platform adapted for your phone. It’s a native mobile experience designed to be fast, clean, and easy to use — so you can spend more time exploring the night sky and less time figuring out how to post.

Share more than just images.
Post high-resolution astrophotography images
Add StarCards© with full capture details
Upload short clips and motion content
Engage through comments and feedback
Discover new objects and techniques
Connect with a global community of astrophotographers

Safer image sharing
Your work matters. Picastro includes built-in protections designed to make your images harder to scrape, copy, or misuse — so you can share with more confidence.

No ads. No clutter. No distractions. Picastro is subscription-based by design. That means no adverts, no spam, and no algorithm-driven content feeds. Just a clean, focused space for astrophotography.

If you’ve ever felt like:
Social media compresses your images Forums are overwhelming or outdated

Your work gets lost in algorithms
You want to learn but don’t know where to start Picastro was built for you.

Join a different kind of space community. Download Picastro and start sharing the night sky — your way.

Comments on Picastro for Android

★★★★★ Jason Young · Jan 29, 2025
Castro is wonderful. It has been a great joy to join this community of Astrophotography! Being able to share high resolution images and discuss the aspects of this hobby with people from around the world is fantastic! The developers listen to members to improve the app and make the improvements! If you are interested in Astrophotography, Castro is the app for you!
★★★★★ Michael Born · Oct 13, 2024
Great app for sharing your astro images in their full uncompressed glory.
★★☆☆☆ J Hayton · Oct 4, 2024
This is a monthly subscription app. No where does it mention that until AFTER you already registered and tried to sign in. Cool. Now he has my email address for free. Speaking of free... No option to even try the platform for free. You must pay to play. App uninstalled.
★☆☆☆☆ Tommy Mackelroy · Oct 23, 2024
2 years in the making, and then it tries to charge you £50 per year without even seeing what is on there. The owner of the app is very passive-aggressive and is unable to take criticism. He sees it as a direct attack on his person. I would steer clear if I were you and don't waste your time. Owner is only interested in making money from his "hobby"
★☆☆☆☆ Jared Holloway · Sep 28, 2024
Took 24 hours to even be able to creat an account due to the two factor identification. (Would not send code to email, then would send all of them together 12 hours later) No way in app to contact for help No mention of having to pay for access. Must pay for a year with no way to test app or features, or even see if you like it. Needs a free version, and a way to pay monthly at the very least.
