Your subs, your projects, your sky — every feature, step by step.
Screenshots show AstroVault as of July 2026 — small details may differ from the live app as we keep refining the experience.
Your account is free forever — and every new account unlocks 14 days of all features, so you can try the full platform before choosing a plan.
Click Start free, enter your email and a password (8+ characters with an uppercase, lowercase, number and special character), accept the terms, and pass the quick security check.
Type — or just paste — the 6-digit code we email you. Didn't get it? Check your spam folder; a resend timer runs for 120 seconds, then you can request a new one.
Choose Free to get going — your first 14 days include every feature regardless. You can upgrade any time from Billing.
Your command center: images captured, data stored, celestial objects, total exposure time — plus tonight's sky conditions, your best targets, and recent activity.
The Sky Conditions and Tonight's Best Targets cards come alive once you add your first observing location — see chapter 06.

Your Dashboard after adding a location.
My Vault is your file home. Drag in a whole night — folders keep their structure, and astro formats are first-class: FITS, XISF, TIFF, camera RAW, plus JPG/PNG and even your equipment logs.
Drop files or entire folders anywhere on the page — subfolders and all. A progress panel tracks every file; uploads run in parallel, so one failure never stops the rest.
New Folder can auto-create the standard calibration subfolders — Light, Dark, Flats, Bias, Flat_Dark — a one-click clean structure for a night's capture.
Double-click to open folders, use breadcrumbs to jump back, and right-click anything for Download (folders arrive as ZIP), Rename, Move to, Add to starred or Move to Black Hole. Multi-select works too: Ctrl/Cmd-click, Shift-click, or drag a selection box.
Add your own tags and notes to any image or folder — organize the archive the way you think, and find anything again by searching your tags.
Keep the tab open while big uploads finish — the progress panel tells you when everything's in, per file.

Drag a folder in — the progress panel tracks every sub.

Calibration subfolders, ready in one click.

FITS next to finished JPEGs — previews, folders and multi-select in one grid.
The heart of AstroVault: a real astronomical viewer in your browser — no desktop software, nothing to install. Double-click any image to open it, then page through the whole folder with ←/→.
FITS/XISF files open on a fast, server-rendered Preview — free for everyone, forever. Switch to the Original tab to decode the real file in your browser for full-fidelity work.
On the Original tab, the Image Controls panel gives you Auto STF (the classic "make the nebula appear" stretch), Linear mode, midtones & shadow sliders, and black/white point fine-tuning.
Shooting one-shot-color? Pick a pattern (Auto Detect, RGGB, BGGR, GRBG, GBRG) and hit Debayer to bring the color out.
Open the Info panel and expand FITS Header to read gain, sensor temperature, exposure, filter and more — straight from the decoded file.
The Original tab — stretching, debayer and the FITS header — is a Pro feature (included free during your 14-day trial). The Preview tab stays free forever.
And there's more. The advanced image viewer turns every frame into a full analysis workbench:
Five stretch modes — auto-STF, arcsinh, log, gamma, linear — with a live per-channel histogram and black/white point control.
Constellation lines, DSO outlines, an RA/Dec grid, compass and scale bar — with live coordinates under your cursor.
Click any star for its radial profile — FWHM, HFR, eccentricity and encircled energy, per star.
Names, types, magnitudes and cross-IDs for every annotated object, linked out to SIMBAD and Aladin.
Tile and split views with synced pan/zoom, plus RGB / SHO / HOO composites.
Tilt inspector, background-gradient map and an image-quality scorecard — see how good a night really was.

The advanced image viewer — annotated objects, star metrics and a full plate solution.
A personal board that moves every target through your real stages: Planning/Capturing → Want to Process Next → Currently Working On → On Hold → Completed.
Click + Add Target and give it a name, target type, RA/Dec, a priority, and an optional description.
Move cards between columns as the project progresses — the board saves instantly.
Open a card to link its light and calibration frames, stacked masters and final images, and add notes — AstroVault tallies integration time, frames and nights for the project.
Timeline History collects every completed project in Timeline or Monthly view.
Free accounts keep up to 5 targets after the trial; paid plans (and the 14-day trial) are unlimited.

Every target, from idea to finished image — drag cards between stages as you work.
Complete a project on AstroBoard and it lands here: an interactive star map where your finished images are pinned at their real coordinates, over constellations and the Milky Way.
Drag to spin the celestial sphere. The Atlas follows your theme — including Red-Night.
Click any marker for an image carousel of that project's finals, plus date, integration, status and RA/Dec. More Details jumps to the full project view.
The Atlas grows as you finish projects — your personal map of everywhere you've pointed your scope.
The Atlas shows your own completed projects — it's your imaging history on the sky, not a target catalog.

Your completed targets, mapped where they live — here, M51 in Canes Venatici.

Click a pin and the project opens — final image, date, status and coordinates.
Two location-aware tools — free for everyone — tell you whether tonight is worth setting up, and what to shoot.
In Profile → Location, name your site, type your Bortle class, and pick the nearest city — coordinates, elevation and timezone fill in automatically. A privacy toggle hides your exact spot from view.
Tonight's sky scored 0–100 (Excellent / Good / Fair / Poor) with darkness & moon-free windows, an hourly seeing strip, dominant factors, and a 7-day forecast.
Your top deep-sky targets for tonight, ranked by a score that blends altitude, darkness hours, moon distance and brightness — with timeline and altitude views per target.
Save multiple locations (home, dark site) and flip between them right from the Dashboard's Sky Conditions card.

An early look at the Astro Planner — night quality, hourly clouds and tonight's best targets.
Catalog what you shoot with, combine it into named rigs, and — if you capture with N.I.N.A.† — let a whole night upload itself.
Under Equipment Management, add telescopes, cameras, mounts, filters, filter wheels, controllers and optics. Mark your guide scope and guide camera with the "Is this a guide…?" option.
Rig Builder combines saved gear into a named setup — telescope, camera and mount, plus filter wheel, guiding and accessories — which you can attach to AstroBoard projects.
In Profile → Account Settings, create an API key, copy it, and paste it into the AstroVault plugin in N.I.N.A. — your subs land in AstroVault the moment they're saved, hands-off all night.
Your originals are never modified — AstroVault receives copies as they're captured.
The small things that make daily use pleasant.
Dark, Light, Space — and Red-Night, which turns the whole interface red to protect your dark adaptation at the telescope.
Find anything by name, or filter by type, tags and sort order from the sliders icon in the search box.
A visual grid of every image you've uploaded, and a quick-access list of anything you've starred.
Deleted items are recoverable, not gone — Restore puts them back where they were, or permanently delete to reclaim space.
Simple model: paid tiers mainly buy storage (10 GB free → 250 GB → 1 TB → 4 TB). Only two things are Pro-gated — everything else is free, forever.
