SkyTonight - Automated Planning
Your personal scheduler. Runs automatically twice daily, computing observable targets from Messier, Caldwell, OpenNGC/OpenIC catalogs, comets and planets. For your exact location and constraints.
Open-source - Self-hosted - Docker-ready
The autonomous astronomy dashboard built for astrophotographers.
MyAstroBoard runs SkyTonight - your personal observation-planning engine. It automatically computes the best targets from international star catalogs, ranks them with AstroScore, and integrates weather, ISS passes, spaceflight events and more into one elegant self-hosted control center.

Why MyAstroBoard
Everything a serious astrophotographer needs - in one self-hosted tool.
No subscription. No cloud. No compromises.
AstroScore Ranking
Every target gets a [0-1] score based on visibility, sky quality, brightness and viewing comfort - so you always image the best target available tonight, not just the first on a list.
Plan My Night
Build your personal observation timeline from SkyTonight results. Reorder targets, check altitude-vs-time charts per object, and export to CSV or PDF for field use.
Astrodex - Your Catalog
A private astrophotography catalog to track your imaged and target objects. Attach your own images, add notes, and cross-reference with SkyTonight results.
Astro Weather Analysis
Weather forecast powered by Open-Meteo, with astrophotography-specific overlays: seeing forecast, cloud transparency, dew risk alerts, and wind analysis for your site.
Equipment Profiles & FOV
Manage telescope and camera configurations. The field-of-view calculator cross-references your setup against SkyTonight targets to highlight the best matches.
ISS & Space Tracking
Real-time ISS position, visible pass predictions for your location, current crew in orbit, upcoming rocket launches, and spacewalk events - all in one place.
Multi-User with Roles
Admin, user and read-only roles. Shared family or club installation. Each user keeps their own preferences, language, theme and planning data.
SkyTonight Engine
Automated observation planning - no manual catalog work.
SkyTonight is the core of MyAstroBoard. It runs in-process, requires no external container, and delivers ready-to-use results every night.
Interactive Sky Map
Polar azimuth/altitude projection with target trajectories. Click any object to see its full profile and altitude-vs-time chart for the night.
Altitude-vs-Time Charts
Per-target interactive Chart.js graphs showing the full night observability window, the astronomical night band, and your altitude constraints.
Comet Tracking
Fresh comet data from Minor Planet Center (JPL as fallback). Comets are ranked and filtered just like DSOs - no separate lookup needed.
Planets & Solar Bodies
All solar system bodies computed with Skyfield ephemeris (de421.bsp). Opposition bonuses included in AstroScore for peak planetary imaging windows.
Your Constraints, Applied
Configure min/max altitude, airmass, object size, moon separation, and observability threshold. SkyTonight filters and scores against your exact setup.
Smart Schedule
Runs automatically 1 hour after astronomical dawn and 1 hour before astronomical dusk. Intelligent clock detection with 6-hour fallback for reliability.
AstroScore
Dimensionless target quality ranking
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].

Privacy & Ownership
Your observatory. Your server. Your data.
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.
- All astronomical data computed locally with Astropy and Astroplan - no external API dependency for core features
- User data (config, observations, plans) stored only in your Docker volume
- Weather data fetched from Open-Meteo (open-source, no key required)
- No analytics, no tracking cookies, no telemetry by default on the application or this website
- AGPL-3.0 license: source code always available, forks must remain open
Quick Start
Up and running in under 5 minutes with Docker.
Requires Docker and Docker Compose. Works on any Linux host.
1
Create the local repository
# Example
mkdir /opt/myastroboard
cd /opt/myastroboard
2
Download the docker-compose file
curl -o docker-compose.yml https://raw.githubusercontent.com/myastroboard/myastroboard/main/docker-compose.yml
3
Start the application
docker compose pull && docker compose up -d
4
Open your browser and configure
# Open http://localhost:5000 in your browser
# Default credentials: admin / admin
# Change the password immediately after first login
http://localhost:5000
Set your location in the Configuration tab. SkyTonight will automatically run its first calculation and results will appear within minutes.
Open Source
Community-driven. Transparent. Contribution-friendly.
MyAstroBoard is developed entirely in public on GitHub with a clear contribution workflow. The codebase is Python 3.11 + 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.
