A live stack, recreated — every Astra gallery refreshes like this while you image.

A session, as your viewers live it

21:42
Shutter opens

You start imaging and publish the collection from Astra — one click, before a single frame exists.

21:43
Link shared

The gallery is live. You send the link to your club, your group chat, your feed.

23:15
Growing

Every thirty seconds the gallery checks for new images. Each finished frame appears as it lands.

04:17
Dawn

The session ends. The finished collection is already published — nothing left to upload.

What your viewers see

No account, no app, no refresh button. The gallery keeps itself current while they watch.

Summer Nebulae · a night in Cygnus

Recreated here — in a published gallery these frames arrive from your telescope.

Built around the log, not the likes

Observe

An honest observation log

Every session catalogued — targets, conditions, integration, notes. FITS metadata read straight from your files.

Equip

Your gear, remembered

Telescopes, mounts, cameras, filters. Seestar owners get presets out of the box — your images arrive already understood.

Publish

One-click galleries

Pick a collection, publish. Thumbnails, lightbox, object data — generated for you, straight from the desktop app.

Live

Auto-refreshing by default

Published galleries poll for new images every thirty seconds. Share the link at dusk; it's still growing at dawn.

Yours

Your data stays yours

Run the whole service on your own hardware if you like. No lock-in, no harvesting — the log lives with you.

Open

Free software, all the way down

Desktop app, gallery service, viewer — every line is AGPL v3. Read it, change it, run your own.

Free software, in the old sense

The desktop app, this gallery service, and every line between them are open. Built that way on purpose — because your observation log is a record of your nights under the sky, and your data should always be yours.
