Plan Your Night.
Capture the Universe.
The free, open-source DSO planner for serious astrophotographers. Real-time tracking, moon conditions, imaging windows, all in your browser.
Track
Monitor every DSO in your list in real time. Live altitude, azimuth, and trend - sorted automatically so the best targets are always at the top.
Focus
Log your sessions, set up your rigs, and frame your targets with the built-in framing assistant. Stay organised across every clear night.
Plan
See upcoming imaging windows scored by altitude, moon illumination, and angular separation. Know exactly when to go out - weeks in advance.
Your Night at a Glance
The Position screen shows every object in your tracker, live-sorted by altitude. See what is rising, peaking, and what you are about to miss - moon illumination, angular separation, and local transit time updating every minute.
Visualize the Night
The Chart screen gives you a detailed altitude plot for each object, from dusk till dawn. Track how altitude, moon position, and visibility change hour by hour in one clear view.
Instantly spot the best imaging windows, transit times, and potential moon conflicts. Add your horizon mask and the chart factors it in automatically.
Find the Perfect Moment
The Opportunities screen scores each upcoming night for your target - altitude, duration, moon illumination, and angular separation combined into a single star rating. Know exactly when to go out, not just if you should.
Frame Your Targets
The Framing Assistant shows exactly how each object fits in your rig. Overlay your telescope and camera field of view on an interactive Aladin sky chart, with full rotation control.
Save your setups so you arrive at the night sky ready to capture the perfect composition - no reconfiguring in the dark.
