Open-source - Self-hosted - Docker-ready
MyAstroBoard runs SkyTonight - your personal observation-planning engine. It computes the best targets from a dozen international catalogues for your exact site, ranks them with AstroScore, folds in weather, the Moon and the ISS - and then keeps the other half of the story: a real observing logbook of what you actually captured, and what it adds up to.
Why MyAstroBoard
No subscription. No cloud. No compromises.
Your personal scheduler. Runs twice a day on its own, computing what is observable from OpenNGC, Messier, Caldwell, Herschel 400, Sharpless, Barnard, Arp, Abell and more - plus comets and planets - for your exact site and constraints, ranked by AstroScore.
Turn tonight's shortlist into a timeline. Reorder targets, check each one's altitude-vs-time chart, see where a meridian flip will cost you minutes, and export to CSV or PDF for the field.
A real logbook: sessions, nights, measured conditions, frames and integration per target, your own rating. Then read it back - hours collected, favourite constellations, and every capture placed on a sky chart.
Every object you have imaged, with your own pictures, notes and equipment. Browse it as a collection, on a photo map of where each capture was taken, or by catalogue. Private, or shared with the household.
Open-Meteo forecasts read the way an imager reads them: cloud cover and transparency, seeing, dew risk, wind, and the dark window between astronomical twilight and moonrise - for your GPS coordinates.
Telescopes, cameras, mounts and accessories, combined into the setups you actually use. The field-of-view calculator checks every SkyTonight target against your gear.
Live ISS position and visible passes, solar and lunar transits, the crew in orbit, upcoming launches and spacewalks - all in one place.
Admin, user and read-only roles. Up to five observing sites, each with its own forecasts and cache. Shared equipment combinations, so club gear lives in one place.
Bring your AllSky camera in - live image, keogram, startrails, timelapse and sensor data on an Observatory tab. Hand a capture to MyAstroShine and get the picture back into your Astrodex.
Plan. Observe. Log.
Plenty of tools tell you what to shoot. MyAstroBoard keeps the other half: what you actually did, and what it adds up to over the years.
A session is a trip, not a row in a table. It has a site, an equipment combination, and one or more nights - each with its own start and end times and its own measured conditions: SQM, seeing, transparency, Moon illumination.
Everything the log knows, read back to you. Hours collected month by month, the object types and constellations you gravitate towards, which gear actually did the work, and how your own ratings line up against the conditions you recorded.
Your log is permanently private. There is no shared mode and no admin-wide view - even on an instance where the Astrodex gallery is shared. A Wishlist keeps what you still want to capture, and knows on its own when a wish has been fulfilled.
SkyTonight Engine
SkyTonight is the core of MyAstroBoard. It runs in-process, requires no external container, and delivers ready-to-use results every night.
A polar sky map with every target's trajectory for the night, a deep-sky table you can narrow down to what fits your camera and your hours, and one AstroScore per object so the best target is at the top - not just the first on a list.
Per-target interactive charts showing the full night: observability window, astronomical night band, your altitude constraints, and your own horizon profile if you have one.
When is this object worth your time? Twelve months of dark-hours-above-your-limit for any target, so a season is planned in one look rather than night by night.
Narrow the deep-sky table by angular size, surface brightness, an altitude window in the hours you can actually observe, whether it fits your camera's field of view, and how much integration it needs - server-side, before the results are cut down.
Fresh comet data from the Minor Planet Center, enriched from JPL. Comets are ranked and filtered exactly like DSOs - no separate lookup.
Minimum and maximum altitude, airmass, object size, Moon separation, observability threshold. SkyTonight filters and scores against your exact setup.
Runs one hour after astronomical dawn and one hour before astronomical dusk. Falls back to a six-hour cycle when the system clock cannot be trusted.
AstroScore
Weighted combination of four sub-scores: visibility (40%), sky quality (25%), object brightness (25%), and viewing comfort (10%). Bonuses for planetary opposition (+0.20) and Messier objects (+0.05). Final value clamped to [0.0, 1.0].
Made for your first night, too
A guided setup wizard gets a fresh install to a first result in minutes. Every target carries a difficulty rating, and a "Tonight for you" panel shortlists what suits your skill level and your gear. The Beginner Catalog is a curated set of objects that reward a small telescope and a first camera.
Nothing is hidden behind a mode switch: the full catalogues, constraints and scoring are always one tab away when you are ready for them.
Also for Space Enthusiasts
Real-time ISS ground track, upcoming visible passes for your location with maximum elevation and duration - and the rare solar or lunar transits.
Upcoming and past rocket launches with countdown timers and video stream links, powered by Launch Library 2.
Current ISS crew and every human currently in orbit. Mission details and crew biographies in one glance.
Aurora forecast for your latitude with activity index and best viewing windows during the night.
Next eclipses with interactive altitude charts for your location. Never miss a celestial event again.
Browser and Web Push alerts, on your terms: your plan is about to start, darkness begins, an ISS transit or an eclipse is minutes away, the aurora index just crossed your threshold, a meteor shower peaks.
Privacy & Ownership
MyAstroBoard runs on your own server, NAS, mini-PC, or home lab. There is no mandatory account, no cloud telemetry, and no vendor lock-in. You control what data is processed and what stays private.
Quick Start
Requires Docker and Docker Compose. Works on any Linux host.
Open Source
MyAstroBoard is developed entirely in public on GitHub with a clear contribution workflow. The codebase is Python 3.14 + Flask on the backend, and vanilla HTML/CSS/JavaScript on the frontend - no heavy framework dependencies.
Licensed under AGPL-3.0: all forks and derivatives must remain open source. Source code for all deployed versions is always available in the repository.
