Description
SSI Planner is the must-have tool designed by and for passionate deep-sky astrophotographers.

Simplify your imaging session planning with a powerful set of tools in a modern, smooth interface:

Light pollution maps and image packs (low-res mode available to avoid heavy downloads) for your targets in OFFLINE MODE — download them in the app to use the planner on the go, without any network connection.

*******************
• OFFLINE MODE: Search for targets even without a network connection. Set GPS coordinates for your location (city name only works in online mode). Target images are displayed even offline.
*******************

• SESSION PLANNER: Visualize optimal targets and their altitude curves, meridian transit times and Moon impact — tailored to your skill level, location (Bortle scale) and imaging setup.
• FULL CATALOG: Explore thousands of objects (Messier, NGC, IC, Sharpless, Arp, Abell, Hash and more) with smart search and filters by type (galaxies, nebulae, clusters).
• SKY FRAMING: Easily locate your target within its constellation in the sky.
• FOV CALCULATOR: Simulate your field of view based on your sensor and focal length to perfectly frame your targets.
• ASTRONOMICAL WEATHER: Check cloud cover and seeing forecasts for your GPS coordinates.
• EPHEMERIS: Track Moon phases and total darkness windows (astronomical night).
• EXPORT: PNG, PDF (online only), N.I.N.A. (Sequence & Target), ASIAIR (Plan), EKOS (Scheduler & Sequence) and APT (XML Plan).
• NEWS: Latest astronomy news.
• GUIDES: Handy references to understand astrophotography terminology.
• Astrophotographer galleries via Astrobin.

* Multilingual: French, English, German, Spanish, Italian and Chinese.
* Built-in night vision mode.

Best experienced on mobile.

SSI Planner is ad-free and fully respects your privacy. Prepare your setup, launch your sequence and let the magic of the cosmos unfold!

The app is regularly updated — we welcome your suggestions and bug reports.

Recent changes:
New: imaging now possible even without astronomical darkness! At high latitudes in summer (Sun never below -18°), the planner now falls back to nautical night (-12°) instead of showing no targets. A warning lets you know the sky stays brighter — narrowband filters (Ha/OIII/SII) recommended.
