Field Briefing
What is Picastro and why it matters
Picastro is an astrophotography app and night sky community built for the people behind the telescope — a place where deep sky, lunar, planetary and solar captures live at full resolution, away from the noise of general photo feeds.
Built for astrophotography
Upload full 120 MB / 72 MP images without compression. RGB, narrowband, mono, smartphone — every capture is welcome.
A real community
Follow astrophotographers, vote in Image of the Week, and get feedback from people who actually understand integration time and gradients.
Craft over clout
No chasing attention. No vanity metrics. Just clear skies, clear feedback, and recognition that rewards the work behind the image.
Common questions
What is Picastro?+
Picastro is a dedicated astrophotography app and community for sharing deep sky, planetary, lunar and solar images. It runs on iPhone, iPad and Android phones and tablets.
Is Picastro free?+
Yes. The Curiosity tier is free forever — browse the full feed, follow astrophotographers and upload up to 15 images. Paid tiers unlock larger uploads and Image of the Week voting.
Why does Picastro matter for astrophotographers?+
Generic photo apps strip your data, compress your image and bury your work. Picastro keeps full resolution, organises by what was captured, and puts your work in front of an audience that knows what they're looking at.
Who is Picastro for?+
Beginners with a smartphone and a tripod, intermediates with a star tracker, and serious imagers running mono CMOS rigs and narrowband filters. Every level of the hobby has a home here.
